The impacts of continuous applications of an organic manure (farmyard manure [FYM], green manure [GM], and wheat straw [WS]) combined with inorganic fertilizers (N, P, and K) on soil parameters and productivity of rice (Oryza sativa L.)–wheat (Triticum aestivum L.) systems were investigated in two long-term experiments under conventional tillage in Ludhiana, India, and Bhairahawa, Nepal. Changes in total and labile soil C and N, and microbiological parameters relative to unfertilized and… 

Long-Term Influence of Nutrient Management on Carbon and Nutrients In Typic-Ustochrept Soils

ABSTRACT Continuous incorporation of green manure (GM) and rice straw residue (RSR) over a long period of time generally improved soil physico-chemical properties. To generate this information,

Long-Term Organic Amendment Application Improves Influence on Soil Aggregation, Aggregate Associated Carbon and Carbon Pools under Scented Rice-Potato-Onion Cropping System after the 9th Crop Cycle

ABSTRACT A field experiment was conducted to investigate the influence of long-term application of organic manures on aggregate stability, associated carbon concentrations and carbon pools as an

Rice straw incorporation and integrated nutrient management effects on carbon dynamics and soil chemical and biological properties

Effect of rice straw incorporation and integrated nutrient management on soil chemical and biological properties and potassium dynamics was studied after 12 years of rice-wheat cropping. Soil samples

Combined effect of tillage-water-nutrient management under rice-wheat agro-ecosystem: A study on chemical indicators of soil quality

Soil available nutrients are very sensitive to change in response to management practices, and are considered to be chemical indicators of soil quality. The present investigation was conducted using

Effect of integrated nutrient management on available phosphorus influencing grain and straw yield of rice ( cv. IR-36 ) in an Alfisol

This experiment clearly brought out the beneficia l role of organic amendment on the availability of phosphorus to rice crop particularly at the later stage of growth.

Microbial biomass carbon and some soil properties as influenced by long-term sodic-water irrigation, gypsum, and organic amendments

Long-term sodic-water irrigation may adversely affect the quality of soil organic carbon along with some soil properties. The extent to which the adverse effects can be ameliorated through the use of



Managing soil carbon and nitrogen for productivity and environmental quality

In this study, we investigated the impact of cropping system management on C and N pools, crop yield, and N leaching in a long-term agronomic experiment in Southwest Michigan. Four management types,

Yield and Soil Nutrient Changes in a Long‐Term Rice‐Wheat Rotation in India

Results show that current fertilizer recommendations are inadequate for maintaining yields of rice and wheat in South Asia and this cropping system may not be sustainable without increased K input to maintain soil K above sufficiency levels.

Enhancing Soil Quality through Residue Management in a Rice-Wheat System in Fukuoka, Japan

A long-term experiment (LTE) on a rice-wheat system was initiated in 1963 at the Kyushu National Agricultural Experiment Station, in Fukuoka, Japan, to determine the effects of continuous application

The role of potassium in sustaining yields in a long-term rice-wheat experiment in the Indo-Gangetic Plains of Nepal

Results suggest that farmers should apply adequate amount of K for higher and sustainable rice and wheat yields.

Long term effects of inorganic fertilizer inputs on crop productivity in a rice-wheat cropping system

Yields of rice and wheat crops of a rice-wheat cropping system in a fixed layout of 3×2×2 factorial partially confounded design exhibited linear declining trend in all treatments, with the highest rate of decline found when 120 kg ha-1 N was applied alone.

Turnover of soil organic matter (SOM) and long‐term balances — tools for evaluating sustainable productivity of soils

Using data from long-term experiments at the Loess-Chernozem site, Bad Lauchstadt und 12 other European sites, the carbon (C) and nitrogen (N) dynamics in soils, the determination of decomposable
