Let's think of the environment as a triangle
Nutrients in the soil interact both synergistically and antagonistically.
You can’t add one without altering the uptake of another nutrient(s).
N, P, and K are the popular ones as they boost plant growth like no other. But the ones ‘at the back of the class’ are just as, if not more, important for nutrient efficiency.
Soil Matters focuses on reducing the reliance on synthetically produced nitrogen, enhancing carbon sequestration, and providing the right balance for nutrient dense crops.
Biology is important because it facilitates nutrient and carbon cycling. Biology is alive and must be fed, nurtured, and treated with care. Plants growing in soils with high biological diversity, that balance naturally, resist diseases much better than soils with low biological diversity. Food sources for soil biology come in form of carbon from decaying plant material, and carbohydrates from root exudates, which are created by photosynthesising plants.
Soil biology can be managed by choosing specific food sources (e.g. plant residues or compost) to stimulate different types of biology.
To assess and improve soil structure, you need to know the type of soil first. Soil type also determines the nutrient holding capacity (CEC & ASC).
Soil structure refers to the way soil particles group together to form aggregates. These aggregates vary in size and shape from small crumbs through to large blocks, or in the worst case, some soils resemble a large, solid, featureless mass.
The structure is what determines the ability of water to soak into the soil and excess water to drain away. It also determines air movement through the soil. The structure is a product of microbial activity combining soil particles into aggregates.
