QTL underlying self-fertility in tetraploid alfalfa
A potential strategy to decrease the levels of self-seed production during the seed increase stages of alfalfa (Medicago sativa L.) synthetic cultivar development is selection for decreased self-fertility. The underlying genetics of this trait have not been elucidated and, therefore, a study was designed to identify genetic determinants of alfalfa self-fertility. An F1 mapping population ...

Fertilizer application timing influences greenhouse gas fluxes over a growing season
Microbial production and consumption of greenhouse gases (GHG) is influenced by temperature and nutrients, especially during the first few weeks after agricultural fertilization. The effect of fertilization on GHG fluxes should occur during and shortly after application, yet data indicating how application timing affects both GHG fluxes and crop yields during a growing season are lacking. We ...

Working principle of organic fertilizer production line
Organic fertilizer machine manufacturers give you a brief introduction to the production process of organic fertilizers. In general, the raw material of organic fertilizer is mostly chicken manure. The first step is fermentation. The purpose of fermentation of manure is to eliminate pests and harmful gases in chicken manure. The chicken manure that is not fermented will burn the plants and can ...

Effectiveness of recovered Magnesium Phosphates as fertilizers in neutral and slightly Alkaline soils
Magnesium phosphates such as struvite (MgNH4PO4 · 6H2O) can be recovered from municipal, industrial, and agricultural wastewaters. However, limited information is available on the beneficial reuse of these recovered products; research has focused on low pH soils. This study determined whether recovered struvite and dittmarite (MgNH4PO4 · H2O) were effective P fertilizers in neutral to slightly ...

What is the production cost of chicken manure organic fertilizer?
What is the cost of producing chicken manure organic fertilizer? How much is organic fertilizer production plant cost? What kind of investment cooperation is beneficial to the farm? 1. Comparison of production equipment investment. The reason for the high ratio of organic manure in the production facilities was that the equipment was put into production. If you work with the farm owner, the ...

Nutrient acquisition and yield response of Barley exposed to salt stress under different levels of potassium nutrition
Abstract: A greenhouse experiment was carried out in 2002 at Jordan University of Science and Technology, Agricultural Experiment Station to examine the effect of potassium fertilization on the response of barley (Hordeum vullgare L.) to different soil salinity levels. Five levels of potassium (0, 0.2, 0.4, 0.6, and 0.8 g K per pot as KCl) and two salt levels (0.75 and 13 ds/m) were investigated ...

Inbreeding depression for fertility and biomass in advanced generations of inter- and intrasubspecific hybrids of Tetraploid Alfalfa
Hybrids between Medicago sativa subsp. sativa L. (hereafter 'sativa') and M. sativa subsp. falcata (L.) Arcang. (hereafter 'falcata') often express heterosis for yield. Yield generally declines when hybrids are inbred due to the loss of desirable dominant alleles or epistatic combinations. We hypothesized that inbreeding sativa–falcata hybrids may show more extensive yield loss than ...

Organic Fertilizer Manufacturing Process Fermentation Mode
Organic fertilizer, commonly known as farm manure, consists of various animal, plant residues or metabolites, such as human and animal manure, straw, animal residues, slaughterhouse waste, etc. Carbon-containing materials, mainly from plants and animals, are applied to the soil to provide plant nutrition as its main function. It not only provides comprehensive nutrition for crops, but also has ...

3,4-Dimethylpyrazole Phosphate Solution
Nitrification inhibitor refers to a class of chemical substances that inhibit the biotransformation of ammonium nitrogen into nitrate nitrogen (NCT). Nitrification inhibitors reduce the formation and accumulation of nitrate in soil so that it can reduce the loss of nitrogenous fertilizer in the form of nitrate nitrogen and the impacting on ecological environment. Some results show that, although ...

Influence of nitrogen fertilizer on Cd and Zn accumulation in rapeseed (Brassica napus L.) biomass
Diffuse soil contamination with heavy metals and Cd in particular is a matter of serious concern. Application of conventional remediation methods usually is not feasible due to the large territories and relatively low heavy metal content. Thus, phytoremediation is seen as an alternative. Rapeseed was grown on Cd and Zn contaminated as well as clean soil under the greenhouse conditions. Solid and ...

Availability of iodide and iodate to spinach (Spinacia oleracea L.) in relation to total iodine in soil solution
Abstract A greenhouse pot experiment was carried out to investigate the availability of iodide and iodate to soil-grown spinach (Spinacia oleracea L.) in relation to total iodine concentration in soil solution. Four iodine concentrations (0, 0.5, 1, 2 mg kg−1) for iodide (I−) and iodate (IO3−) were used. Results showed that the biomass productions of spinach were not ...

Grain legumes in northern great plains
Cropping systems in the Northern Great Plains have shifted from fallow-based to legume-based systems. The introduction of grain legumes has impacted soil organisms, including both symbiotic and nonsymbiotic N-fixing bacteria, pathogens, mycorrhizae and fauna, and the processes they perform. These changes occur through effects of legume seed exudates, rhizosphere exudates, and decomposing crop ...

Fertilization and blending alternatives for irrigation with desalinated water
Received for publication April 29, 2008. In arid-zone agriculture where available irrigation water is saline, desalination is becoming an attractive method for increasing yields and reducing negative environmental consequences. However, irrigation with desalinated water can be problematic if essential nutrients, including Ca, Mg, and S, removed during reverse osmosis, are not reintroduced. We ...

Lettuce cationic nutrition and yield, and soil chemical characteristics as affected by vanadium application to leaves or soils
Lettuce plants (Lactuca sativa, L., cv. "trocadero") were grown in pots filled with an Alfisol Udalf or an Andisol Udand soil, under greenhouse conditions. Treatments consisted of adding vanadium to soils (0, 100, 250, 500 and 10001mg1kg1 or as foliar sprays (0, 10, 25, 50, and 1001mg111. Soil chemical characteristics, the cationic nutrition of lettuce and their yields were assessed. No ...

What is an organic waste composting appliance, its purpose, and its working principle
Now, a large amount of waste is generated every day, both at the domestic level and industrial level. It is most important to handle waste effectively. The food is deserte into landfills free of methane which is dangerous for the earth as an entire. Composting is the best method to handle the waste. How to successfully compost? Composting means recycling green waste composter ...

Irrigated, no-till corn and barley response to nitrogen in Northern Colorado
Converting irrigated, conventional-till (CT) systems to no-till (NT) production systems can potentially reduce soil erosion, fossil fuel consumption, and greenhouse gas emissions. Nitrogen fertilization effects on irrigated corn (Zea mays L.) and malting barley (Hordeum distichon L.) yields in a corn-barley rotation were evaluated for 6 yr on a clay loam soil to determine the viability of using a ...
