[1] Surface soils hold the largest terrestrial organic carbon pool, although estimates of the world’s soil organic carbon storage remain controversial, largely due to spatial data gaps or insufficient data density. In this study, spatial distribution and storage of soil organic carbon in China are estimated using the published data from 34,411 soil profiles investigated during China’s second na...

Sodic soils have immense productivity potential, if managed through proper technology interventions. Bio-compost is prepared by composting pressmud and gypsum received from waste material of mining can be used to reclaim sodic soils. Field experiments were conducted during the June-November 2018 2019 at ICAR - Indian Agricultural Research Institute, Sub Regional Station, Pusa (Samastipur), Biha...

Nitrogen (N) in plants is generally diagnosed by a soil test and plant tissue analysis.However, such analyses are costly in terms of time and money and are not easily accessible byresearchers and extension workers, let alone farmers. Alternative cost-effective methods arerequired for rapid analysis of the N status of crops and to guide N management in wheat. Theobjective of this study was to as...

A field experiment was conducted during 2013-14 to 2015-16 at Central Soil Salinity Research Institute, Regional Station, Lucknow find out the alternate rice (Oryza sativa L.)- wheat (Triticum aestivum L.) cropping system under partially reclaimed sodic soils. Four systems, viz. L.), sorghum (Sorghum bicolor)-berseem (Trifolium alexandrinum), sweet basil (tulsi) (Ocimum basilicum L.)-matricaria...

The study focused on investigating the contribution of reclamation strategies saline-sodic soils and their impacts soil fertility characteristics. In this study, treatments were denoted as: SG1 SG2 (23.8 47.7 ton/ha spent grain); TC1 TC2 47.6 compost); Azospirillium in inoculation with seed (Az); Az + (Az+SG1); (Az+TC1); mineral fertilizers (NPK); control (CK). All mixed pots 30 kg soil. result...

Accumulation of soluble salts in arid areas which are similar to most regions of Iran is inevitable in soil surface and profile because of low precipitation and high evaporation. High concentration of soluble salts in soil profile caused severe problems for root water uptake thus plant growth stopped. Reducing soil salinity to optimized content by leaching and avoiding soil pounding must be con...
