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 ...

Conventional agriculture can lead to reduced soil organic matter and depletion in soil fertility. For that reason, Food and Agriculture Organization of the United Nations (FAO) recommends organic matter incorporation to soils to increase their agronomic quality. This work studies the effect of the transition to organic farming on chemical and biochemical properties of a loam soil (Xerofluvent), ...

The European Food Safety Authority guideline on risk assessment identifies pesticide exposure scenarios for non‐target wildlife, however this scheme is not applicable to non‐agricultural grassland. For example, different habitats and human utilisation on golf courses attract bird communities that differ from those found in agricultural fields with annual crop cycles. The present study ...

Background The present investigation was undertaken to assess the residual influence of organic materials and biofertilizers applied to rice and wheat on yield, nutrient status, and economics of succeeding mung bean in an organic cropping system. The field experiments were carried out on the research farm of IARI, New Delhi during crop cycles of 2006 to 2007 and 2007 to 2008 to study the effects ...

Castor is an important non-edible oilseed crop of the family Euphorbiaceae with great utilitarian value in industry, agriculture and pharmaceutical sectors. The presence of hydroxyl group and double bonds in ricinoleic acid (D-12-hydroxyoctadec-cis-9-enoic acid) imparts unique chemical and physical properties for castor oil which makes castor oil a vital industrial raw material and ...

Different irrigation methods in wheat (Triticum aestivum L.) result in different water and nutrient use efficiencies and, ultimately, plant growth. A field experiment was conducted during the 2006–2007 and 2007–2008 crop cycles to investigate the effects of furrow irrigated raised bed planting and the effects of flood irrigated conventional planting on growth and productivity in winter wheat. In ...

Improving soil organic matter and soil fertility are important factors in the sustainability of sugarcane (Saccharum spp.) production. A 3-yr field trial was established in 2004 on a sandy Alfisol in Florida to compare the effect of organic and inorganic nutrient sources on sugarcane production. The three nutrient sources were (i) mill mud (filter cake, cachaza), (ii) local standard fertilizer, ...

Mike, our Agronomist, was recently asked a few questions about irrigation and nutrition for a magazine.  What quality parameters can be influenced (fruit size, flavour, firmness, shelf life, etc.)? All crop quality parameters can be enhanced through correct use of nutrition. Having the ideal strength and balance of nutrients at all stages of the crop cycle ...

Everyone who works in agriculture is aware of the basic lifecycle of crops: plants are seeded, they are nourished and they grow, they are harvested, and what is not consumed by (us) higher life forms is returned to the soil—where it is broken down through mineralization and by microorganisms so that it can be used to nourish the next cycle of crops. That relatively simple scenario is ...

Owing to their high water retention, the volcanic ash-soils of the Northern Andean highlands (páramos) can be considered as natural ‘water storage tanks’ for drinking water and for irrigation. Vegetation plays an important role in transferring rain to the soil and in controlling the soil water content. To assess this role, we quantified the stemflow process under rainfall simulations for seven ...

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 ...

Perpetuating cereal cover crops through self-seeding may increase adoption by reducing risk and cost. Winter rye (Secale cereale L.), wheat (Triticum aestivum L.), and triticale (x Triticosecale Wittmack) were used to develop self-seeding cover crop systems in a soybean [Glycine max (L.) Merr.]–corn (Zea mays L.) rotation. Cereals were planted and managed chemically and mechanically in varying ...

To evidence the multidimensionality of the soil quality concept, we propose the use of data visualization as a tool for exploratory data analyses, model building, and diagnostics. Our objective was to establish the best edaphic indicators for assessing soil quality in four no-till systems with regard to functioning as a medium for crop production and nutrient cycling across two Illinois ...

Rice farmers in Spain experience two major problems with their rice crops: After the flooding and fertilisation of the rice fields algal growth rapidly develops and covers the surface of the water in the paddy. This greatly reduces the availability of sunlight received by the seedlings until they have grown above the water level. This results in early stage plant loss which can be severe. The ...

Sweet sorghum [SS; Sorghum bicolor (L.) Moench] is a potential biofuel crop for the Great Plains. Sweet sorghum was compared with corn [Zea mays (L.)] and grain sorghum for potential ethanol yield, energy use efficiency, and greenhouse gas (GHG) emissions at seven dryland site-years in Nebraska. Seasonal rainfall ranged from approximately 340 to 660 mm. Soils were deep with medium texture at all ...

The rapidly increasing amounts of compost applied to California farms can be traced to numerous factors — better crops, fewer disease problems, greater emphasis on product quality, mandated state recycling goals, savings in disposal costs and savings in chemical inputs. And then there’s the factor of friendship, longtime personal relationships that build trust between composters and farm ...

Coupling winter small grain cover crops (CC) with liquid manure injection may increase manure nutrient capture. The objectives of this research were to quantify manure injection effects using target swine (Sus scrofa) manure N rates of 112, 224, and 336 kg N ha–1 on CC plant density, fall and spring shoot biomass, N, P, and K uptake and subsequent corn (Zea mays L.) yield. A winter rye (Secale ...

As you round the final bend of Road 95 through the groves of walnut and almond trees, it would be easy to miss Muller Ranch, but for the cluster of pickup trucks circling the driveway. Yet amidst these swaying Yolo County orchards sits a stunning third-generation, family-owned farm, thriving with several thousand acres of processing tomatoes, specialty peppers, corn, wheat, canola, cucumbers, ...
