Abstract Aims The aim of study was to quantify the temporal change soil organic carbon content in relation agricultural management for a dry sandy arable and derive C sequestration potential. Methods We analyzed data from long-term field experiment with three crop rotations different cereal proportions, two levels straw application (removal/return) combination four mineral nitrogen rates (40 … ...

the aims of the present study was to evaluate the level of aflatoxin b1 (afb1) in feedstuffs (corn silage, corn, dried alfalfa, cottonseed meal, cottonseed, soybean meal, canola meal, barley, wheat bran, concentrate, sugar beet pulp and wheat straw) that collected from dairy herds in khorasan razavi province that classified according to milk yield in very high (>10000 kg/day), high (5000-10000 ...

Hydrochars are an alternative form of biochar produced by hydrothermal carbonisation (HTC), a potentially cheaper and greener method. In this paper, the effect multiple variables on hydrochar properties was investigated. Waste biomass converted to via microwave-assisted carbonisation. The were temperature, solution ratio (water-biomass ratio), time, particle size, pH acetone washing. measured y...

Arbuscular mycorrhizal (AM) fungi, a group of widespread fungal symbionts crops, could be important in driving crop yield across rotations through plant–soil feedbacks (PSF). However, whether preceding crops have legacy effect on the AM fungi subsequent is poorly known. We set up an outdoor mesocosm rotation experiment that consisted first phase growing either one four pre-crops establishing an...

This study was conducted to determine the common animal feeding practices as well types of feeds used in cattle enterprises located central county Erzincan province. For this purpose, data were obtained by conducting a face survey with 401 dairy breeders. Percentages which moved their animals pasture March, April, May and June respectively 2.6%, 56.7%, 39.3% 1.3%. Cattle breeders tended general...

Each year, millions of tons of agricultural residues such as wheat straw are produced worldwide. In this paper, we describe ongoing efforts to solve technological, infrastructural, and economic challenges to using this straw for bioenergy and bioproducts. Among these challenges, silica in straw forms a low-melting point eutectic with potassium, causing excessive slagging deposits in boilers. Th...
