How does ph influence soil fertility
WebJan 24, 2024 · Soil pH is another important aspect of soil fertility. pH is not a plant nutrient, but rather is a measure of the acidity of the soil. Most crops grow best when the soil pH falls between 6.2 and 6.8. This is the range in which plant roots can best absorb most nutrients from the soil. Organic matter WebApr 11, 2016 · The overall effect on soil pH is close to neutral. However, in reality, we often over apply ammonium-based N fertilizers to compensate for the nitrate leached from the soil, thus soil pH is reduced over time, partly because of the accumulation of H + released through nitrification process.

WebWhen the pH of a soil is increased, the release of H from carboxyl groups helps to buffer the increase in pH and at the same time creates the CEC (negative charge). With an increase in organic matter, the soil recovers its natural buffer capacity; this means an increase in pH in acid soils (Figure 19). WebFeb 19, 2024 · Parent material composition has a direct impact on soil chemistry and fertility. Parent materials rich in soluble ions-calcium, magnesium, potassium, and sodium, are easily dissolved in water and made available to plants. Limestone and basaltic lava both have a high content of soluble bases and produce fertile soil in humid climates.
