🌱 [Monday #Agronomic #News!] The rain continues to cause significant delays in the fields: diseases are spreading, access remains limited, and some plots still haven't been sown. For those who haven't finished sowing, there are still options available. In the south of France, you can consider growing crops such as sunflower, soybean, millet, sorghum, maize, and buckwheat. However, in the north, the options are more limited, with maize and buckwheat being the most viable choices. 🌟This week's topic: #Phosphorus What is Phosphorus? Phosphorus is a vital #nutrient for plants that helps them store and use #energy from sunlight. It's like a battery for plants, storing energy during #photosynthesis and releasing it when needed. Plants get phosphorus from the #soil, but it's often hard to access because it doesn't move easily and can get stuck in the soil. 🌱 Challenges with Phosphorus: ▶ Limited Mobility: Phosphates move 10x less than nitrates, requiring roots to be very close. ▶ #Soil pH: In calcareous clay soils (common in central France), calcium binds with phosphorus, making it unavailable. Acidic soils have similar issues with aluminum or iron. 🌾 Solutions: Direct Application: Applying mineral phosphorus near roots can be effective, especially when protected by sulfur in calcareous soils. However, relying solely on this method isn't sustainable due to the finite availability of mined #phosphorus. #PlantStrategies: ▶ Root Development: More roots mean more entry points for phosphorus. ▶ Rhizosphere Acidification: Root exudates can make phosphorus bioavailable. Plants like horse bean, lupinus, and buckwheat excel at this, making cover crops and companion crops effective. 🌿 Innovative Practices: A farmer in the US grew localized radishes on future crop seed lines. These radishes pick up phosphorus and nutrients, creating fertility packs when they decompose, benefiting the next crop sown in the same row. These examples encourage us to think about the potential we can unlock by better understanding and working with nature. #Agriculture #SoilHealth #SustainableFarming #PhosphorusManagement #InnovativeAgriculture
