Industrially produced N-fertilizer is essential to the production of cereals that supports current and projected human populations. We constructed a top-down global N budget for maize, rice, wheat 50-year period (1961 2010). Cereals harvested total 1551 Tg N, which 48% was supplied through fertilizer-N 4% came from net soil depletion. An estimated (737 Tg) crop equal 29, 38, 25 kg ha(-1) yr(-1) wheat, respectively, contributed by sources other than fertilizer- or soil-N. Non-symbiotic N2...
Abstract Food security involves the sustainable utilization of soil and land resources. Zero‐tillage (ZT) practice is a proponent better resource utilization, to improve physical condition, potential sink atmospheric carbon. However, impact varies across climates, over ZT history, cropping systems, depths. A meta‐analysis was performed, based on 4,131 paired data from 522 studies spread globally, evaluate effect in comparison conventional tillage, condition (bulk density; mean weight...
Healthy soil is critical to human health and for achieving sustainable development goals (SDGs). Although India attained self-sufficiency in food production, realising zero hunger, good health, no poverty remains a challenge. In this paper, we summarize key features of Indian soils capture existing developing trends research assess our preparedness meet soil-linked SDGs. We begin by taking stock soils, their nutrient status, quality explore some the rapidly emerging areas realize goal. Given...
South Asia is a global hotspot for climate change with enormous pressure on land and water resources feeding the burgeoning population. The agricultural production systems are highly vulnerable in region primarily dominated by small marginal farmers intensive farming practices that had favored loss of carbon (C) from soil. This review discusses potential soil crop management such as minimum/reduced/no-tillage, use organic manure, balanced integrated plant nutrient application, precision...
Abstract Direct-seeded rice (DSR) seeds are often exposed to multiple environmental stresses in the field, leading poor emergence, growth and productivity. Appropriate seed priming agents may help overcome these challenges by ensuring uniform germination, better seedling stand establishment. To examine effectiveness of sodium selenite (Na-selenite), selenate (Na-selenate), zinc oxide nanoparticles (ZnO-NPs), their combinations as for DSR seeds, a controlled pot experiment followed field over...
Soil samples were obtained from a long‐term trial conducted on silty loam at Sardar Vallabhbhai Patel University of Agriculture & Technology, Modipuram (Meerut), in 2007–2008 to study the effects various combinations conventional and zero‐tillage (ZT) raised‐bed systems soil aggregation associated organic C fractions 0‐ 5‐cm 5‐ 10‐cm depth rice–wheat ( Orysa sativa L.– Triticum aestivum L.) rotation. Macroaggregates increased under ZT rice (direct‐seeded or transplanted) wheat rotation...
Earthworms commonly occur within the soil. They alter physico-chemical and biological regimes of soil through their activities, such as burrowing, casting, feeding propagating, therefore are known 'ecosystem engineers'. Through they provide a number ecosystem services which ecologically socio-economically important. This article reviews role earthworms in improving structural functional properties, serves key determinants economic benefits for farmers. A methodology evaluation agro-ecosystem...
The prevalence of water-intensive cropping systems in tandem with the use traditional irrigation methods such as flood have resulted alarming water scarcity levels many countries like India. Enhancing and nutrient efficiency agriculture using drip is accentuated to address rising fertilizer crisis. Input efficiencies may be further improved by optimizing doses schedules. In present study, crop productivities wheat-moongbean-maize system, were evaluated for surface (SDI) subsurface (SSDI)...
