Precipitation of the area, addition of organic and farmyard manure, cropping systems and fertilizers usage are few important.
Dear Deeksha,
The quantitative evaluation of predicted climate change effect on soil health is a difficult task due to uncertainties in weather forecast. Soil health is the continued capacity of a soil to function as a vital system, within ecosystem and land use boundaries, to sustain biological productivity, maintain the quality of air and water, environment, and promote plant, animal and human health.Soil health is a composite set of measurable physical, chemical and biological attributes related to functional soil processes, which can be used to evaluate soil health status as affected by management practices and climate change. Nitrogen, Carbon, Conservation, Crop rotations, Soil cover, Crop residue, Soil drainage, Marginal land, Organic farming. health in relation to climate change should consider the impact of range of predicted global change drives such as rising atmospheric carbon dioxide levels, elevated temperature, altered precipitation and atmospheric nitrogen deposition on physical, chemical and biological functions of soil.
Following are the major consequences of global climate change on soil health.
Soil physical parameters
1. Soil texture
2. Soil structure and Aggregate stability
3. Porosity
4. Infiltration and plant available water
5. Bulk density
6. Rooting depth
7. Soil surface cover
8. Soil temperature
Soil chemical parameters
1. Soil pH
2. Electrical conductivity
3. Sorption and Cation exchange capacity
4. Plant available nutrients
Soil biological parameters
1. Soil organic matter
2. Light fraction and Macro organic matter (Labile organic matter)
3. Soil carbon and C:N ratio
4. Potentially mineral sable C and N
5. Soil respiration
6. Soil microbial biomass
7. Enzyme activity
8. Mitigation of adverse effect of climate change on soil health
9. Soil temperature
10. Soil structure and Soil aggregation

The impact of climate and the use of the necessary fertilizers for each soil is very important-----
Farmers practices, crop rotation process, use of natural manure, variation of productivity, trees cover and trees management.
Soil organic carbon,cropping system, precipitation,soil and air temperature, Tillage practices in the area
Parameters linking soil health, climate change and crop residue management.
Healthy soil should be productive i.e. give high economic yields of a target crop, soil is productive, when it has combinations of the four parameters (1) optimum and balanced nutrients, which are available to crop for uptake, (2) optimum amount of soil moisture for making sure crop nutrient uptake, photosynthesis and other processes take place optimally, (3) Optimum amount of soil organic carbon for moderating soil physical, chemical and biological properties of the soil and (4) optimum soil and air temperatures. The measures of the four can be used to link the soil health-climate change-crop residue management. Take for example measurements of moisture, organic carbon, plant nutrients and temperature have bearing on soil health, climate change and crop residue management is in conservation Agriculture studies.
Practicing and adopting Conservation Agriculture (CA) is the right option. CA is an integrated ecosystem approach to regenerative sustainable agriculture and land management. The CA is based on the three main principals (Continuous no or minimum mechanical soil disturbance , permanent maintenance of soil mulch cover including crop biomass , stubble and cover crops and the inclusion of legumes crop in the rotation). It can increase and improve soil organic matter, soil moisture and sequester CO2 in the soil and limiting it is emission into the atmosphere.
