Nitrogen fixation of Sulla under Mediterranean conditions
Sulla coronaria (L.) B.H. Choi & H. Ohashi (=Hedysarum coronarium L.) is a Mediterranean forage legume grown extensively in rainfed Italian environments. Here we report the field quantification of its seasonal and annual N fixation, using the 15N isotopic dilution (ID) method, the influence of various nonfixing reference species on these estimates, and the allocation of fixed N between the ...

Nitrogen-Fixing Bacteria
Opinion piece: sustainability gets supercharged thanks to all-new formulation designed to drive yield As a farmer your job is as simple as it is intensely complex: sustainably produce food to feed the world. A key component of profitable agriculture is using the exact amount of inputs to drive yields. Fertilizer, your largest expense, must be critically timed to achieve the best results. ...

Controlling Nitrogen with Clinoptilolite
With skyrocketing prices on the fertilizer market, and record high contamination levels in runoff from soil leaching, solutions for fixing nutrients in the root zone are of paramount importance. The price of nitrogen fertilizer is always in flux, but as of recently there is a distinct and obvious spike. Fertilizer prices are on the rise. Meanwhile the broad use of fertilizer in agriculture has ...

Growth and nitrogen fixation in high-yielding soybean: Impact of nitrogen fertilization
In high-yielding soybean [Glycine max (L.) Merr.] environments, N uptake during seed-filling may be constrained when the late-season decline in biological nitrogen fixation (BNF) is coupled with insufficient soil N. Three N-fertilization strategies were compared with a control (N0) on soybeans in 2006 and 2007 in a high-yield soybean-maize (Zea mays L.) rotation experiment established in 1999. ...

Processing organic fertilizer by using crop straw
The crop straw organic fertilizer production line is advanced composting fermentation process, inoculates high-speed and high-efficiency fermentation bacteria, which makes the straw cellulose rapidly decompose and transform, and all kinds of pathogenic bacteria, weed seeds and aphid eggs are killed, and produce the bio-organic fertilizers with strong stability and full range of nutrient. We ...

Heritability of N2 fixation traits, and phenotypic and genotypic correlations between N2 fixation traits with drought resistance traits and yield in peanut
Drought stress reduces growth and yield in peanut (Arachis hypogaea L.) and also reduces nitrogen fixation (NF). Peanut production in drought prone areas should be enhanced by the development of cultivars that can fix more nitrogen (N) under drought conditions. The aims of this study were to estimate heritability for NF and to estimate phenotypic and genotypic correlations among traits related to ...

The key problems in the production of organic fertilizer production line
A complete organic fertilizer granulation process production line requires a lot of preparation work before it is put into production, such as the parameters of the organic fertilizer production equipment, the fermentation process of the fertilizer, the maturity of the organic fertilizer, the drying process, and the granulation process. Only these parameters are determined only after it is good ...

Application of microbial bacterial fertilizer in agricultural organic fertilizer production line
Bio-fertilizer is a kind of product that leads to the specific fertilizer effect of crops caused by the life activities of microorganisms, and it is a kind of finished fertilizer in the organic fertilizer production line. It has a huge effect on crop growth and soil nutrition. Here we introduce the application of microbial bacterial fertilizer in the organic fertilizer production line. 1. The ...

A New Generation of GMOs
Is synthetic biology on its way to our farms, markets and tables? Thousands of researchers will descend on Boston this fall for an event billed as the world’s largest gathering of synthetic biologists. The field is evolving so rapidly that even scientists working in it don’t agree on a definition, but at its core synthetic biology involves bringing engineering principles to ...

One crop, two ways, multiple benefits
Nitrogen fixation is one of the best examples of cooperation in nature. Soil microbes – naturally occurring bacteria in the soil – work with plants to pull nitrogen from the air. They turn the nitrogen into a form the plant is able to use. In return, the plant lets the microbes eat some of the sugars it makes. Faba beans (also called fava beans) are one example of plants that work ...

Soil Nutrients and Field Health: what you Need to Know
The soil on your field is like the brain to your body. It tells your crops everything they need to know to produce a healthy yield; how many organisms live there, what the pH balance is, whether or not something is performing well… For the brain, if something isn’t performing well, the body can react catastrophically. The same thing happens with soil. If you have too much ...

Reuse of Dairy Lagoon Wastewater Through SDI in Forage Crops
Abstract California has become the leading dairy products producing state in the USA. This has resulted in farms commonly milking several thousand cows per day. The care and feeding of the animals has produced large waste streams commonly collected and stored in lagoons. Environmentally safe handling and reuse of the lagooned wastewater is the objective of this study. A system of Subsurface Drip ...

Ammonium fixation in selected California decomposed granites
Abstract Revegetation on disturbed, low organic matter content, decomposed granite (DG) substrates are limited by low plant-available moisture and nitrogen. Data from a single DG site in northern California, USA, showed that a significant fraction of the ammonium from fertilizers or organic matter mineralization was fixed into silicate interlayer positions. To evaluate the broader relevance of ...
