Book Description
Management practices that may increase soil organic matter (SOM) storage include conservation tillage, especially no till (NT), enhanced cropping intensity, and fertilization. My objectives were to evaluate management effects on labile [soil microbial biomass (SMB) and mineralizable, particulate organic matter (POM), and hydrolyzable SOM] and slow (mineral-associated and resistant organic) C and N pools and turnover in continuous sorghum [Sorghum bicolor (L.) Moench.], wheat (Triticum aestivum L.), and soybean [Glycine max (L.) Merr.], sorghum-wheat/soybean, and wheat/soybean sequences under conventional tillage (CT) and NT with and without N fertilization. A Weswood silty clay loam (fine, mixed, thermic Fluventic Ustochepts) in southern central Texas was sampled at three depth increments to a 30-cm depth after wheat, sorghum, and soybean harvesting. Soil organic C and total N showed similar responses to tillage, cropping sequence, and N fertilization following wheat, sorghum, and soybean. Most effects were observed in surface soils. NT significantly increased SOC. Nitrogen fertilization significantly increased SOC only under NT. Compared to NT or N addition, enhanced cropping intensity only slightly increased SOC. Estimates of C sequestration rates under NT indicated that SOC would reach a new equilibrium after 20 yr or less of imposition of this treatment. Labile pools were all significantly greater with NT than CTat 0 to 5 cm and decreased with depth. SMB, mineralizable C and N, POM, and hydrolyzable C were highly correlated with each other and SOC, but their slopes were significantly different, being lowest in mineralizable C and highest in hydrolyzable C. These results indicated that different methods determined various fractions of total SOC. Results from soil physical fractionation and 13C concentrations further supported these observations. Carbon turnover rates increased in the sequence: ROC

Book Description
Land And Soil Are Non-Renewable Natural Resources. The Nature Has Taken Thousands Of Years To Create An Inch Of Fertile Soil. Mismanagement Of This Precious Resource Is A Sin Against Nature And Will Play Havoc With The Fortunes Of The Country. Many Parts Of The Country Have Already Come To The Brink Of Devastation Through Injudicious Usages, Over Exploitation Of Natural Resources Resulting In Unsustainable Productivity Of Crops.Modern Concept Of Cropping System Is Based On The Principle Of Effective Utilization Of Soil Water, Nutrients And Light For Sustainable Crop Productivity. This Book Gives The Basic Principles And Broadly Accepted Definitions Terms Frequently Used In The Literature. A Short-Review Of The Cropping Systems Work Done In The Tropics, Particularly In India Is Presented.In This Revised Edition, Contents Of All The Chapters Have Been Revised To Give Orientation Towards Management Of Sustainable Crop Production Systems. A New Chapter On Farming System Is Also Added In Tune With The Latest Trends. Information Available On Perennial Crop-Based Cropping Systems, For Example High Density Multi Species Cropping Systems Involving Coconut And Arecanut Is Updated. The Various Management Aspects Of Sustainable Cropping Systems Are Discussed And The Research Methodology That Could Be Adopted Is Elucidated. Possible Future Lines Of Work Are Given In The Final Chapter.This Book Will Prove To Be Of Immense Value Not Only To The Research Workers But Also To The Teachers And Students And Above All Farmers And Individuals Who Are Desirous Of Improving Sustainable Crop Production Systems.
