Soil microbial metabolism and invertase activity under crop rotation and no-tillage in North China
Soil samples were collected at both jointing and maturing stages of maize and wheat to compare the effects of 4-year no-tillage (NT) and conventional tillage (CT) on seasonal variations of microbial biomass carbon (C), metabolic quotient, and invertase activity in a sandy loam soil in North China. Soil invertase activity significantly increased (P < 0.05) from summer to spring of the next year ...
متن کاملSoil Quality and the Benefits of Crop Rotation, Reduced Tillage, and Manure Application
U tah has a small, but regionally (and nationally, in the case of tart cherry) significant tree fruit industry producing over $23 million in orchard receipts (US Census Bureau, 2009) from about 8,000 acres statewide (42% tart cherry, 23% peaches, 21% apple, with the remainder in sweet cherries, apricots, pears and other minor crops; USDANASS, 2007). Hence, establishing proper interpretive guide...
متن کاملاثر منابع مختلف کود و سیستم‌های خاک‌ورزی متفاوت بر عملکرد ذرت دانه‌ای و عناصر غذایی خاک
In line with sustainable agriculture development, an experiment was conducted including tillage as the main factor in two conventional systems (plowing and mixing fertilizer with soil) and no tillage (leaving residuals of green manure and direct corn sowing). The fertilizer resources were T0: control, T1: barley green manure without chemical and manure fertilizers, T2: barley green manure with ...
متن کاملEffects of green manure crops and tillage practice on maize and rice yields and soil properties
Improper tillage with no manure may cause a range of undesirable processes (destruction of soil structure, accelerate erosion, depletion of organic matter and fertility). A field experiment was conducted to observe the change in soil properties after incorporation of green manure crops and to find out the residual effect of green manure crops along with tillage on maize and rice yields during 2...
متن کاملEffect of crop residue and nitrogen levels in yield and yield attributing traits of rice under Rice-Wheat Cropping System
A 3- years (2015, 2016 and 2017) field study was carried out at National Wheat Research Program, Bhirahawa, Rupandehi, Nepal to evaluate the influence of crop residues and nitrogen levels on rice. The experiment was conducted in split plot design with three replications. Main plots were two crop residue levels (with crop residues of 30 cm wheat stubble and without crop residues) and sub plots c...
