Effect of climate and cultivation on nitrogen and organic matter reserves in Indian soils. (). Effect of deforestation and cultivation on soil CEC and content of exchangeable bases: a case study (). Exchange equilibria of potassium in soils, V Effect of natural organic matter on K . The organic matter pool turns over at approximately 3% per year. So if you had 2% organic matter (% organic carbon) and had a soil bulk density of g/cm 3 ( tonnes soil per 10cm layer) = t C/ha per year which supplies 46kg N/ha, 11kg P/ha and .

Prolonged cultivation of 90 years did not result in a decrease in the rates of losses of C, N, and P on the silt loam soil. Conversion of concentration data to area based total C, N, and P budgets resulted in a decrease in the differences seen between cultivated and uncultivated soils. Cultivation Effects on the Amounts and Concentration of Carbon, Nitrogen, and Phosphorus in Grassland Soils' H. Tiessen, J. W. B. Stewart, and J. R. Bettany* ABSTRACT Cultivation has substantially reduced the organic matter contents of many prairie soils.

Specifically, pH influences solubility andCited by: The presence - or absence - of soil organic matter (SOM) has important implications for agricultural productivity. It could also have significant implications for global climate due to its role as a source/sink of carbon. Therefore, it is important to understand the issues related to the accumulation or loss of SOM, to use what we have learned from experiments to make sound decisions about.

The differential response of each region to cultivation is hypothesized to be due to differences in both climate and management practices (crop cycles, fertilization). These findings suggest that estimates of soil C loss due to cultivation should be based on an array of factors, and that it is unlikely that a constant relative C loss occurs in any by: Effect of climate and cultivation on nitrogen and organic matter reserves in Indian soils.

Nitrogen is a key component of soil organic matter. Apart from carbon, hydrogen and oxygen, it is the most abundant element in living tissue.

It is also by far the most abundant element in the atmosphere. Yet, paradoxically, higher forms of life are incapable of drawing directly on this vast reservoir of by: 4. Organic matter is the life of soil. It enables a soil to perform efficiently its primary function of supporting plant growth.

Its endemic deficiency in tropical soils, particularly those under the influence of arid, semiarid and sub-humid climates, is a major factor contributing to their low by: The climate var- ies from 0 to 25 °C MAT and from near 0 to a little over cm MAP. There is no overlap between the climate ranges of India and the Great Plains (Figure 1).

These data previously were used in a study of cultivation effects on soil organic matter in the Great Plains (Burke et al. JENNY, H., and RAYCHAUDHURI, S.

Predicted relationship of relative soil organic C losses from cultivation to annual precipitation in (50% clay, 20% silt), loam (20% clay, 40% silt), and sandy loam (10% clay, 30% silt) soils. Given the central role soil plays on the global carbon (C) and nitrogen (N) cycles and its impact on greenhouse gas emissions, there is an urgent need to increase our common understanding about sources, mechanisms and processes that regulate organic matter mineralization and stabilization, and to identify those management practices and processes which mitigate greenhouse gas emissions, helping increase organic matter stabilization.

Nitrogen release from organic matter was calculated by nitrogen total on the organic matter treatment minus control divided by nitrogen content on the 5 t organic matter.

The results showed that N-NH4. The article refers to the stock and sequestration of organic carbon in soils rich in carbonates, particularly in rendzinas. It presents factors determining sequestration of organic carbon in rendzinas in comparison to other soils, and describes the mechanisms of accumulation of organic matter in.

The study confirmed the effects of climate on C reserves in the soil. However, this study did not estimate the total C stock in Indian soils.

The Himalayan zones, with dense forest vegetation, cover a fifth part of India and store a third part of the country reserves of soil organic carbon (SOC).
