Ronan Mulligan, Teagasc Walsh Scholar, Claremorris. The SoilCares Manager app is a sophisticated app that connects with the SoilCares Scanner and provides the user with information about soil fertility levels for N, P and K based on the current situation on your field (soil type, crop grown, nutrient availability, etc.). Farmers turn to fertilizers because these substances contain plant nutrients such as nitrogen, phosphorus, and potassium. The proportions of clay and organic matter found in soil influence its fertility. 1. It provides. To understand its importance, it’s important to understand its role in soil development. Promotes plant growth: Soil fertility: Fertile soil supports the growth of plants. What could the potential impact on aquatic systems be if N and P fertilizers are consistently applied to soil in excess of plant needs? Soil plays a vital role in the survival of living beings on earth. First, there’s the carbon cycle. Even other insects and animals get food by pasturing on plants. Join now.
