Background Pig manure utilization and valorization is an important topic with tightening regulations focused on ecological and safety issues. By itself pig manure is a poor substrate for biogas production because of its excessive nitrogen content relative to available organic carbon. Such substrate is alkaline, and methanogenesis can be suppressed, and so additional substrates with high organic...

The combination of organic manure and inorganic fertilizer plays a role in increasing crop yield nutrient efficiency, but such effectiveness varies with crop, soil, management, climate. Here, 6-year field experiment was conducted to evaluate the effects substituting on yield, grain protein content, nitrogen phosphorus efficiency under winter wheat-summer maize cropping system Anthrosol. Five tr...

The aim of the present study was to examine the effect of a replacement diet with organic, semi-whole-grain products derived from Triticum turgidum subsp. turanicum (ancient) wheat on irritable bowel syndrome (IBS) symptoms and inflammatory/biochemical parameters. A double-blinded randomised cross-over trial was performed using twenty participants (thirteen females and seven males, aged 18-59 y...

Using ileal digestible amino acids in feed optimising will intensify feed protein utilizing and decrease nitrogen excretion to the environment. The study determined the apparent ileal digestibility (AID) coefficients of amino acids in barley, wheat, oats, triticale, maize, and dehulled oats in the diets of 180 Ross broiler chickens (aged 24–35 days). The birds were fed semi-purified diets that ...

the slow pool, with decadal turnover times, while 5% of the SOC is found in the rapidly cycling active fraction, Previous studies of no-till management in the Great Plains have with turnover times ranging from hours to months (Folshown that increased cropping intensity increased soil organic carbon (SOC). The objectives of this study were to (i) determine which soil lett, 2001; Shaffer et al., ...

mulches often use for weed control, hold soil moisture, decrease soil temperature, soil fertility, soil conservation, soil against rain and soil quality in organic farming. a field experiment was conducted to evaluate the effect of different wheat residue and sunflower densities on sunflower growth and yield during 2007 growing season at the research field of birjand university. the experimenta...

The multi-billion dollar organic food industry is fueled by consumer perception that organic food is healthier (greater nutritional value and fewer toxic chemicals). Studies of the nutrient content in organic foods vary in results due to differences in the ground cover and maturity of the organic farming operation. Nutrient content also varies from farmer to farmer and year to year. However, re...

To find suitable farming management approaches in the semi-arid climate of Iran, we set up an experiment combining three farm practices with four crop rotation systems over growing seasons (two winter and two summer seasons), from 2018 to 2020. The comprised: intensive (IF, inorganic inputs, removal residues soil, weeds chemically controlled), organic (OF, a return 30% mechanically integrated (...
