Maintenance of soil physical health at its optimum level is essential for sustainable crop production and rational use natural resources without jeopardizing their quality. The ongoing conventional tillage practices for using intensive ploughing and removal residue from the field have resulted in an increase surface crusting, soil compaction, erosion, decrease water infiltration and ultimately aggravation overall physical health deterioration. In recent years, many...
Among the several causes, critical low soil organic matter status is predominant for decline in health and consequent fall crop productivity.Over years, availability of traditional source amendment, viz.cattle manure drastically declined due to various reasons (domestic uses as fuel plastering kachha houses).The present study highlights that there are many alternative sources amendments available country which have tremendous potential improve productivity, rejuvenate enhance dying total...
In this article we review how different management technologies like integrated nutrient management, tillage practices, mulching, addition of clay, surface compaction, conservation tillage, use polymers, etc. can favourably modify the soil physical properties bulk density, porosity, aeration, moisture, aggregation, water retention and transmission properties, processes evaporation, infiltration, run-off loss for better crop growth yield. The central idea is to suggest that if appropriate are...
Soil microbial communities are important drivers of biogeochemical cycling nutrients, organic matter decomposition, soil carbon, and Greenhouse gas emissions (GHGs: CO 2 , N O, CH 4 ) influenced by crop management practices. The knowledge on the impact conservation agriculture (CA) bacterial diversity, nutrient availability, GHG in semi-arid regions under rainfed conditions is vital to develop sustainable agricultural practices, but such information has not been systemically documented....
The present study was conducted in 2009-10 with the objective to monitor effect of restorative soil management practices on biological quality. experiment initiated 1995 a strip-split-split plot design three replications. Sorghum and castor were grown two-year rotations. procedure comprised two tillage treatments: conventional (CT) minimum (MT; main plots), residues sorghum stover (SS), Gliricidia loppings (GL), no residue (NR; sub-plots), nitrogen levels 0 (N0) 90 kg ha -1 (N90)...
A pot experiment was conducted on cadmium (Cd)–enriched (0, 40, 80, 120, 160 mg Cd kg−1 soil, using CdCl2), untreated (Unamended), 3% sewage sludge–treated (SS-amended), and farmyard manure–treated (FYM-amended) soils to evaluate the phytoextractibility of by three oilseed crop species (viz., Brassica juncea, napus, Eruca sativa). Visual observation showed that at or above 40 ppm Cd, some light chlorotic symptoms, resembling iron (Fe) chlorosis, appeared after 2 3 weeks germination. The...
A long term experiment (2005–2012) was conducted in rainfed semi-arid tropical Alfisol at Hayathnagar Research Farm of Central Institute for Dryland Agriculture, Hyderabad, India. The aim this to study the long-term impacts graded levels surface crop residue application on carbon (C) pools, aggregate associated C, C lability index and their relationship with yield. a randomized block design (RBD) minimum tillage (MT). Experimental treatments comprised four sorghum residues (@ 0, 2, 4 6 t...
A long-term field experiment was conducted at Hayathnagar Research Farm (HRF) of ICAR-Central Institute Dryland Agriculture with the objectives to assess effect soil management practices viz tillage, residue application and N levels on phosphorus fractions, their interrelationships among themselves, impact P availability pool, crop yields uptake. The results study clearly indicated that use residues had a significant all fractions in soils, except water-soluble (WSP) not significantly...
A long term experiment was conducted for 11 years to study the effects of soil and nutrient management practices on fertility additive quality indices in rainfed Alfisol, at Hyderabad, India. The treatments were comprised conventional tillage (CT) minimum (MT) as main factors, sorghum stover (dry) @ 2 t/ha (SS), fresh gliricidia loppings (GL) no residue (NR) application surface sub-treatments N levels 0, 30, 60 90 kg N/ha sub- sub castor-sorghum yearly rotation. results indicated that after...
A long term experiment was conducted at Central Research Institute for Dryland Agriculture 14 years to evaluate the effect of low tillage and cost conjunctive nutrient management practices in terms productivity, sustainability, profitability energy use efficiency sorghum-mung bean system rainfed semi-arid tropical Alfisol.
