The effects of 34 years cultivation on organic carbon content of the loess derived soils were studied in Golestan province, northern Iran. Soil organic carbon (SOC) showed significant decrease in most of cases. The minimum and maximum SOC decreases were 4 and 51.14 Mg C ha-1/30 cm for 34 years. In a few cases there was an increase in SOC up to 16.93 Mg C ha-1/30 cm over the period of 34 years i...

The extreme climate of the northern Great Plains of North America requires cropping systems to possess a resilient soil resource in order to be sustainable. This paper summarizes the interactive effects of tillage, crop sequence, and cropping intensity on soil quality indicators for two long-term cropping system experiments in the northern Great Plains. The experiments, located in central North...

The objective of this study was to compare organic carbon (C) accumulation in plantations (PL) and natural succession (NS) established on fallow lands along a 50-year chronosequence in the eastern mixed forest subzone of Quebec (Canada). Aboveand below-ground woody biomass were estimated from vegetation measurement surveys, and litter and soil (0–50 cm depth) C from samplings. At the year of ab...

We hypothesized that the integration of trees into agricultural land-use systems can reduce NO., leaching and increase subsoil N utilization. A field study was conducted on a Kandiudalfic Eutrudox (Ochinga site) and a Kandic Paleustalf (Muange site) in the subhumid highlands of Kenya to measure changes in soil NO, and water to 200-cm depth for one rainy season in four land-use systems (LUS): (i...

Soil organic carbon (SOC) pool is the largest among terrestrial pools. The restoration of SOC pool in arable lands represents a potential sink for atmospheric CO2. Restorative management of SOC includes using organic manures, adopting legume-based crop rotations, and converting plow till to a conservation till system. A field study was conducted to analyze soil properties on two farms located i...

Field experiment was conducted at Soil Science Research Farm of SHUATS Prayagraj, (U.P.) on, sandy loam soil to” Influenced Vermicompost and Biofertilizer on Physico-chemial properties under hybrid Maize (Zea may L.)” during kharif season 2022. There are nine treatment combinations were comprised in randomized block design with three replications. The results showed that the application PSB had...

Agronomic practices, climatic variables, and soil conditions are key factors in crop productivity. Although the effects of soil chemical properties and water and agronomic crop management are known, there is little information about effective soil depth and its influence on crop productivity. Since most crop fertilization systems are based on the productive potential associated with climatic co...

the performance of new forage brassica plants were studied in ilam, iran, during 2012-2014 in a field experiment using a randomized complete block design with four replications. the treatments included, different forage crops perko, buko, oilseed radish, berseem clover, and the combination of three plants ramtil, phaselia, and clover. the studied traits consisted of plant height, forage yield, ...
