Question

What are the factors affecting organic matter levels in the soil?how this level of organic mattrr can be increased.

Answer 1

here's your answer

a continuous soil cover of living plants, which together with the soil architecture facilitates the capture and infiltration of rainwater and protects the soil;

a litter layer of decomposing leaves or residues providing a continuous energy source for macro- and micro-organisms;

the roots of different plants distributed throughout the soil at different depths permit an effective uptake of nutrients and an active interaction with microorganisms;

the major period of nutrient release by micro-organisms coincides with the major period of nutrient demand by plants;

nutrients recycled by deep-rooting plants and soil macrofauna and microfauna.

soil organic matter levels commonly increase as mean annual precipitation increases

Answer 2

Following are some factors that effect the organic matter level in soil:

1- Climate

2-Drainage

3-Natural vegetation

4- Rotations, residues and plant nutrients

5-Temperature

6- Tillage and cropping

We can increase the organic matter level in soil by adding plant litter, sludge and animal manure... By reducing tillage...By Crop Rotation
