What are the most effective ways to manage animal waste in agriculture?

The best way to handle animal waste is primarily to reduce the amount produced. This means a drastic reduction in animal production worldwide and a modification of diets towards a predominately plant based on. Meat will be an occasional luxury for people. Any manure produced will be readily and easily absorbed by natural biological systems and not cause the pollution and environmental degradation that it does now. Over 80% of agricultural land is devoted to livestock that produces only 18% of food calories but contributes 80% of the food related greenhouse gases. This cannot continue if we are to reduce the impact of climate change.

It is not waste, manure is a resource! Used correctly manure is an excellant fertilizer. Manure contains N,P and K. It also is a great source for secondary and micro nutrients.

Establishing an infrastructure to produce biogas from farm waste from animal waste or dead animals. Then, if the environment and climatic conditions do not help, we can dig a technical hole in which we periodically bury all the waste at a good depth so that we ensure that it decomposes after a record time with the addition of some auxiliary materials and the presence of Common decomposition conditions

As Iain Tolhurst has set out, the best way to ensure that our shared environment is not damaged by excreta from farmed animals is to move away from industrially & artificially breeding animals into farming. Particularly in the Global North, we need to rapidly transition to plant-based biosphere management & food systems. By ending industrial farming of animals, non-human animal excreta (including greenhouse gases) will be able to come back into balance with the overall biosphere. We will also free up land to end the current climate, biodiversity, impoverishment & public health crises around the world, through community-scale biosphere management. The Global North & wealthy people must return the biosphere to Indigenous custody.

En milieu rural, il serait difficile de trouver régulièrement les auditifs et des instruments d'analyse des fumiers. Pour cela il faudrait proposer des solutions de contrôle pour couvrir des zones déterminées

The right source of animal waste refers to the quality and composition of the manure, which depends on the type, age, diet, and health of the animals, as well as the bedding and storage methods used. The right source of animal waste should match the nutrient needs and availability of the crops or plants that will receive it, and avoid excess or deficiency of nitrogen, phosphorus, potassium, and other elements. To achieve the right source, you should test the manure regularly, use appropriate additives or treatments to enhance its value or reduce its odor, and separate the solid and liquid fractions if possible.

Proper management of animal waste must take into account that manure itself is a perfect culture medium for both micro and macro organisms. That is why it is important to make the environment not suitable for growth. This can be obtained through variations in pH, temperature and/or water content. Or all of them. A microbiological predator, such as Lactobacillii, can be introduced, which also prevents the hatching of fly eggs. Biotechnologies such as Hermetia spp. are also useful here. From a biochemical point of view, increasing the C/N ratio is also a great tool, since free N is responsible for odors and fly attraction. A good source of C can be prepared specifically, as a C3 culture. Later compost, vermicompost, biogas...

La producción de biogas por la fermentacion anaerobia de los desechos animales junto con desechos vegetales es una muy buena opción que ya se está aplicando en granjas de engorde de cerdos, al ser el purin un líquido de dificil y cara eliminación además de ser un contaminante muy concentrado. El biogas generado es una fuente de energia util para diversas actividades de la propia granja. Son residuos que se eliminan a km 0.

I take a precision approach even to manure management. I ensure my animals' diet optimizes digestive health and waste composition. I phased out hormones or antibiotics that can contaminate effluent. Ration adjustments also reduced nitrogen and phosphorus surpluses to align soil needs with nutrient outputs. Thoughtfully sourcing waste right from the animal first allows me to divert over 85% of effluent towards beneficial reuse.

Para reducir los principales contaminantes del estiercol líquido generado en las granjas como son el nitrogeno amoniacal y el fósforo, es imprescindible realizar un tratamiento biológico aerobio por lodos activados que tiene un elevado rendimiento en estos casos al tener las balsas de acumulación un tiempo de residencia hidraulica de más de 180 días. Es imprescindible filtrar el purin liquido con un tornillo prensa que retira paja, solidos y otros plasticos (crotales) para tener que depurar solo la fraccion líquida con la DQO y el amonio disueltos. El aporte de oxígeno es directamente proporcional a la cantidad de nitrogeno amoniacal ( 4,2 kg de oxígeno por cada kg de nitrogeno amoniacal).

If we move away from having animals in farming then we will need to harvest our own manure as animal manures provide vital NPK but are especially important for their phosphorus content. Getting phosphorus from alternative sources like rocks involves environmentally damaging mining. So, to get it from the only source left if we eliminate animal manures and rocks is our own human manure. This would mean a change in the way we currently process our own human manure.

Getting waste application rates right is critical to maximize utilization efficiency while avoiding environmental hazards from surpluses. For artisanal approaches like fertilizer teas, I use small but precise batches for controlled testing and troubleshooting to refine ideal formulations that don't overwhelm target croplands or pastures before broad application. Managing by meaningful metrics, not rough timetables, ensures every ounce of waste sustains ecological cycles effectively.

La cantidad requerida debe proyectarse en relación a un análisis de suelo, el cual nos muestra la composición orgánica y nutricional de nuestro terreno, en base a ellos determinamos el nivel de compostaje de nuestra materia orgánica buscando mejorar estructura del suelo, o, en su defecto un aporte nutricional, generalmente de nitrógeno

Animal weste sould be bring under process to make it compost and use it to land soil according to soil fertility, if the soil fertility is better, the compost should use lesse and if the soil fertility is not good, the rate should be more

Regenerative grazing of livestock of single or multi-species flocks in the same paddocks under ultra high density(High animal numbers over small areas) for as short a time as possible (As short as 1 hour per paddock) while still non-selectively utilizing the available forage (up to 90% utilization), and allowed proper rest periods (Up to 19 months depending climatic conditions) after such treatments is key to managing the rate of deposition and concentration of "waste".

El fertilizante se mantendrá en las balsas de acumulación y se reducirá los niveles de nitrogeno amoniacal hasta el punto que se requiera para solo abonar los campos colindantes mediante riego por aspersión (no teniendo que utilizar tractores que deban de esparcir el desecho sólido). En la época de lluvias es dificil de regar ya que el suelo está empapado y no admite más líquido. Si se realiza con tractor es imposible acceder a los campos por el barro. El líquido en la balsa siempre va a estar agitado y aireado con lo que no va a oler mal.

Timing matters as much as technique when stewarding animal waste. As a conscientious farmer, I follow seasonal rhythms when directing effluent flows across my operation. I store excess materials over winter when fields lie fallow then apply just before spring planting needs, with secondary applications timed to support crop growth spurts or mitigate pest pressure during summer. For pasture rotations, I assiduously track rainfall patterns and soil moisture levels to identify optimal windows for supplementing vegetation via organic matter without impeding grass productivity or composition.

En relación a la aplicación de esta materia orgánica, el momento oportuno debe ser en el intermedio o transición de un periodo de lluvias a seco, o de baja intensidad, debido a que se aplican grandes cantidades por árbol, una alta precipitación puede generar lavado y escorrentia del producto hacia las calles del cultivo, dónde sera eficiente pero no oportuna

Animal west which changed to compost should be used only during soil preparation and it is the right time for using the the animal west compost

Dentro de la lista, este es el más elemental. La inmadurez del desecho animal puede entrar en competencia elementos en el suelo y la relación C:N necesaria para terminar el ciclo del abono y las necesidades del cultivo. Elementos de valoración: Tiempo de madurez del abono, edad del cultivo.

When the time of animal impact and adequate rest is planned efficiently for either forage/grazing only or in a system where both cash crops and pasture (alternating grazing in and out of seasons) is utilized the cycle of grazing and planting/harvesting can be adapted with planning to always be on time. Adapting to such a system will utilize cash crop stubble (Or inter-cropped forage cover crops) while fertilizing for future crop planting and when cash crops are developing the pasture can be utilized. In a pasture/grazing only system it allow the manure to alternately be deposited over all areas in every season over its a life span. Because rest of more than 12 months is allowed, the same paddock won't be utilized at the same time each year.

The right place for animal west or compost depends on the crop which is planned to be cultivated, if there is planned to cultivate bigger seed the animal west compost should be used around 3 CM under soil

El aporte del agua depurada se realizará mediante conducciones de riego por aspersión con lo que va a aprovecharse totalmente la cantidad justa y necesaria para aportar los nutrientes al suelo o campo. El agua filtrada no va a contaminar las fuentes ya que ha sido tratada para eliminar el amonio y los nitratos generados en el proceso de depuración y va a ser filtrada por el propio terreno. Se puede llegar con el riego a zonas de difícil acceso ya que solo ha de llegar una tubería.

For precision application as fertilizer, irrigation or energy inputs, I installed piping and containment infrastructure to target recipient sites without risks of uncontrolled dispersion or hazardous exposures. Site-specific handling curates customized waste-to-resource pathways region by region while protecting the broader ecosystem.

Match the animal, its care expectations, your time, and its market value for food, milk, blood, or food to the environment. Be concerned with the waste use and its impact based on your land surface size. Remember to utilize your land in cubic, not square.

En principal lugar donde buscamos mejorar nutrición y composición del suelo es en la zona de absorción, está comprende lo que es la parte de crecimiento radicular la cual, generalmente, está en los primeros 50 a 90 centímetros desde la base del tallo, esto varia de acuerdo a la especie vegetal

In my master's research, I observed that rural producers store waste outdoors, in piles. Despite there being uncontrolled decomposition there, the issue is that besides the bad smell, attraction of vectors, aesthetic degradation of the environment, there are risks of these wastes coming into contact with groundwater and surface water, leading to contamination of these resources. Additionally, the waste may contain pathogenic microorganisms harmful to human health, as well as residues of medications not metabolized by the animal's body. The appropriate action would be to deposit them in a closed location and treat them through composting, so they can be used as organic fertilizer, distributed according to the nutritional needs of the plants.

Animals were created in, and as a part of, an ecosystem. Allowing them to function as that will always deposit the manure and urine in the right place when coupled with correct grazing planning management. Some great examples of livestock management under such conditions in the wild, sharing such areas with the big 5 even, are seen in all over Africa.

I continuously explore innovative ways to extract value from waste beyond land application alone. Vermicomposting uses worms to rapidly biodegrade manure into nutrient-rich teas while insect larvae like black soldier fly grubs efficiently upcycle effluent into high-protein feeds. Keeping an open and creative mindset has allowed us to establish entire secondary revenue streams meeting local sustainability needs while responsibly diverting over 90% of our farms waste outputs.

When possible and able to compost and treat animal waste you can bring an added value to this fertilizer in addition to ease of handling in bags for various crops.Additionally, when properly managed, animal waste can be both profitable and environmentally friendly. The quality of land, water, and air can be threatened by improper handling, so sustainable practices are crucial.

Another alternative option is to use Black Soldier Fly (BSF) larvae to offer a sustainable solution for agricultural waste management. These larvae efficiently convert various organic materials into nutrient-rich biomass, serving as valuable feed for livestock and aquaculture. Introducing BSF larvae reduces waste volume, minimizes odors, and produces high-quality compost. This innovative approach contributes to a closed-loop system, recycling nutrients within the agricultural ecosystem.

I am a big fan of the circular economy type of operations in agriculture. Bio industrials bio energy and various other value added waste products are going to be in higher demand for the future. I would encourage ranchers to make sure they do extensive homework before getting into a deal with a company looking to purchase your livestock waste.

Se puede usar o transformar en muchas opciones, una de las más recomendadas es la descomposición en el tiempo con lombrices rojas californianas buscando la humificacion de esta materia orgánica, la cual generalmente mayor contenido de carbono oxidable disponible para la microfauna del suelo

Composting is the best way to treat animal waste. In addition to reducing its volume, a fundamental aspect for sustainability, it also generates high-value organic fertilizer, along with the elimination of pathogenic microorganisms. However, it is necessary to compost properly for this to occur. With the transformation into organic fertilizer, there is also a cost-saving on the rural property since the organic fertilizer used in vegetable gardens and orchards, for example, is generated on-site, without the need for external purchase. It is also necessary to pay attention to the nutritional needs of each crop to then distribute the treated organic fertilizer accordingly.

Besides applying animal waste to the land, there are other options to manage it in a sustainable and profitable way. For example, you can compost it to produce a stable and odorless organic fertilizer, or anaerobically digest it to produce biogas and biofertilizer. You can also process it to produce animal feed, biochar, or bio-based products, such as plastics, fibers, or chemicals. These options can help you diversify your income, reduce your dependence on fossil fuels, and contribute to the circular economy

Some alternatives to the natural utilization in pasture or grazing land fertilization are available. Some that can improve the quality of the manure for use in crop fields and farming are composting, vermicomposting and charging of Johnsson Su bioreactors. The main drawback is the laborious task of collecting and mixing or application of the manure elsewhere than where than animal deposited it. Animals are livestock, and work for a living. Man should not work for animals, cleaning their waste and bringing them feed.

Los desechos tanto animales como de cualquier tipo van a ser un recurso en los años venideros y han de aprovecharse como fuente alternativa y que no generará huella de carbono al ser reutilizados en la misma instalación.
