Healthy soil is essential to a circular economy
To achieve the Dutch government's objective of realising a circular economy in the Netherlands, it is essential to maintain the productivity of the country's farmland. Healthy soil produces renewable raw materials for biobased products. However, declining carbon levels in arable Dutch soil is inhibiting our ability to meet this objective, and continued global warming is standing in the way of a ...

Advantages and precautions of NPK organic fertilizer granulator
The humus in organic fertilizer increases the content of soil organic matter, which is beneficial to the formation of good soil structure, especially the increase of water stable aggregate structure, so as to improve the tightness, aeration, water retention and heat status of soil, and has a good effect on the water, fertilizer, air and heat conditions that determine the soil fertility. It is ...

Six effects of organic matter on maintaining soil fertility
The content of soil organic matter is closely related to the level of soil fertility. Although organic matter only accounts for a small part of the total amount of soil, it plays a significant role in maintaining soil fertility. The manufacturer of organic fertilizer production equipment introduces six important functions of organic matter to maintain soil fertility. 1. Provide nutrition for ...

Progressive N limitation of plant response to elevated CO2: a microbiological perspective
Abstract A major uncertainty in predicting long-term ecosystem C balance is whether stimulation of net primary production will be sustained in future atmospheric CO2 scenarios. Immobilization of nutrients (N in particular) in plant biomass and soil organic matter (SOM) provides negative feedbacks to plant growth and may lead to progressive N limitation (PNL) of plant response to CO2 ...

Fertilizer vs. organic matter contributions to nitrogen leaching in cropping systems of the Pampas: 15N application in field lysimeters
Abstract Nitrogen (N) export from soils to streams and groundwater under the intensifying cropping schemes of the Pampas is modest compared to intensively cultivated basins of Europe and North America; however, a slow N enrichment of water resources has been suggested. We (1) analyzed the fate of fertilizer N and (2) evaluated the contribution of fertilizer and soil organic matter (SOM) to N ...

Multivariate analysis and visualization of soil quality data for no-till systems
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 ...

Sugarcane response to mill mud, fertilizer, and soybean nutrient sources on a sandy soil
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, ...

Italian ryegrass management effects on nitrogen supply to a subsequent potato crop
There is increasing use of Italian ryegrass (Lolium multiflorum Lam.) as a green manure in potato (Solanum tuberosum L.) rotations; however, effects of its management on soil N supply to the subsequent potato crop are unknown. Fertilizer N management and plow-down date for a preceding Italian ryegrass crop, ‘Lemtal’, on soil N supply to a subsequent potato crop, ‘Russet Burbank’, was determined ...

High-Yielding corn response to applied Phosphorus, Potassium, and Sulfur in Nebraska
Nutrient management recommendations may change as yield levels and efficiency of crop production increase. Recommendations for P, K, and S were evaluated using results from 34 irrigated corn (Zea mays L.) trials conducted in diverse situations across Nebraska. The mean yield was 14.7 Mg ha–1 with adequate fertilizer applied. The median harvest index values were 0.52, 0.89, 0.15, and 0.56 for ...

Dairy manure compost effects on corn silage production and soil properties
Accumulation of dairy manure compost has created a need to identify alternative uses for this plant nutrient source. This field study determined compost effects on corn (Zea mays L.) silage production, nutritive value, and soil characteristics for three growing seasons following incorporation of dairy manure compost at 0, 35, 70, and 105 Mg dry matter (DM) ha–1. Yields from subplots receiving ...

Effect of implementing organic farming on chemical and biochemical properties of an irrigated loam soil
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), ...

Organic fertilizer drum granulator production line
Organic fertilizer drum granulator production line Organic fertilizers are rich in nutrients needed for crop growth and can continuously supply crops with them.In addition to mineral nutrients, the decomposition of organic matter in soil produces carbon dioxide, which can be used as the raw material for crop photosynthesis and is conducive to the improvement of crop yield.Providing nutrients is ...

Observing the nitrogen cycle in a green manure trial on an organic farm
As part of a 5 year Federal Government funded Landcare project in the Gippsland area of Victoria, a number of on-farm trials have taken place. One of these trials was monitoring a range of green manures on a certified organic vegetable farm. The demonstration trialled and compared 6 different green manure crops each year for 3 years against a control. The control was immediately adjacent to the ...

Results from the ground up
Maintaining soil health and increasing bushels Soil health is the most important aspect of your farm fields. Without healthy soil, you face a tough challenge each year. When your soil profile is strong and not deficient in any nutrients or minerals, you increase your chance of a successful growing season. More than anything, healthy soil gives you the chance to increase your bushels. If your soil ...

Organic Soil for Healthy Crops and Gardens, Black Worm Castings, Vermaplex
Creating a healthy organic garden is easier than you think. It all starts with the soil. As a gardener or farmer your goal is healthy plants that yield plentiful of flowers, fruits and vegetables. Your first priority should be the soil, it is the key ingredient to a thriving garden. Plants receive their nutrients from the soil. They are dependent on a soil full of microorganisms such as ...

Safe seed-placed fertilizer practices and equipment limits
When it comes to applying seed-placed fertilizer, it is important to find the suitable application rate for each specific soil type and composition. But it is also important to understand that seeding equipment and technology is a factor, and may impact growers’ fertilizer rates. The seed-safe rate for fertilizers relies on numerous factors. Crop choice, soil composition, pH levels, ...

Unlocking Precision and Sustainability with Portable Soil EC Detectors
For millennia, farmers have tilled the land, guided by intuition and tradition. But beneath the surface, in the hidden realm of the soil, lies a powerful language waiting to be deciphered. A language not of words, but of electrical whispers, dictating the very foundation of plant growth and ecosystem health. This language is spoken in terms of Electrical Conductivity (EC), and to understand it, ...

How three U.S. mini-farms are sowing the seeds of global food security
Tiny, biointensive operations show smallholder farmers from around the world how they can grow far more food than conventional approaches. Her face shaded by a wide-brimmed straw hat, Olawumi Benedict is cheerfully tending to her “little babies” — kale seedlings growing in shallow wooden flats until they’re hardy enough for transplantation into soil beds. Three miles over ...
