Land application of sugar beet by-products: effects on Nitrogen mineralization and crop yields
Land application of food processing wastes has become an acceptable practice because of the nutrient value of the wastes and potential cost savings in their disposal. Spoiled beets and pulp are among the main by-products generated by the sugar beet (Beta vulgaris L.) processing industry. Farmers commonly land apply these by-products at rates >224 Mg ha–1 on a fresh weight basis. However, ...

Fertilization of pinus pinea L. seedlings with a sewage sludge-based compost
Two experiments were conducted to evaluate the effect of a sewage sludge-based compost (SSC) on the growth and mineral composition of containerized Pinus pinea L. seedlings. In the first experiment, five different substrates were tested: four binary mixtures of SSC and peat (100% SSC, 75% SSC, 50% SSC and 25% SSC, by volume) without fertilization, and a control substrate (peat-based substrate + ...

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 ...

Dairy cattle manure improves soil productivity in low residue rotation systems
Mineral fertilizer alone may not sustain soil productivity in cropping systems that return little crop residues to the soil, unless additional organic residues and/or manure is applied regularly to the soil. The objective of the present study was to assess the long-term effects of mineral fertilization (No fertilizer, PK, and NPK) and manure addition (0 and 20 Mg ha–1 yr–1) on soil physical and ...

Response of nitrogen uptake and partitioning to critical nitrogen supply in oat cultivars
Nitrogen uptake and partitioning in oat (Avena sativa L.) are not well documented. A greenhouse study was conducted to determine the critical timing of N supply on the growth, N uptake, and partitioning. Plants grown in plastic pots were subjected to five N fertilization regimes: (i) control, N supply from seedling to physiological maturity (PM); (ii) N supply from seedling to flag leaf; (iii) N ...

Rainfall simulation in greenhouse microcosms to assess bacterial-associated runoff from land-applied poultry litter
Runoff water following a rain event is one possible source of environmental contamination after a manure application. This greenhouse study used a rainfall simulator to determine bacterial-associated runoff from troughs of common bermudagrass [Cynodon dactylon (L.) Pers.] that were treated with P-based, N-based, and N plus lime rates of poultry (Gallus gallus) litter, recommended inorganic ...

Dietary cation–anion difference and tetany index of timothy forage fertilized with liquid swine manure
Incidence of metabolic disorders increases when dairy cows (Bos taurus) are fed forages that have a high dietary cation-anion difference (DCAD) (>250 mmolc kg–1 dry matter, DM) or high grass tetany (GT) index (>2.2), both associated with high forage K concentration, often caused by applications of liquid swine manure (LSM). We determined how DCAD and GT index of timothy (Phleum pratense L.), ...

Zonejection: Conservation tillage manure nutrient delivery system
Manure application in minimum till (MT) systems is a challenge worthy of attention because residue cover is a keystone for environmental protection. To develop a system combining zone tillage and manure application into one operation (zonejection), two experiments were conducted. In Exp. 1, liquid swine manure (LSM) was applied in fall or spring for two site years (A, B). In Exp. 2, LSM was ...

Worst Water Weeds #4: Cattails
Most people call them cattails, although you’ll come across those who refer them as “punks” or even as “corn dog grass.” If you happen to be British, you’re more likely to call them “bulrushes” or “reedmace.” They are members of the scientific family of Typhaceae, large marsh plants sporting the telltale brownish compact ...

Operation precautions of NPK fertilizer granulation coating
In the NPK fertilizer manufac?turing process, a coating process is added to make a slow-release fertilizer. Slow-release fertilizer is also called controlled-release fertilizer. The release rate of nutrients in fertilizers can be controlled to a certain extent for continuous absorption and utilization by crops. After the fertilizer is coated, it can reduce the loss of fertilizer nutrients, ...

Potato response to a polymer-coated urea on an irrigated, coarse-textured soil
Controlled release fertilizers, especially polymer-coated urea (PCU), have been shown to reduce nitrate (NO3) leaching while maintaining potato (Solanum tuberosum L.) yields, but cost has been prohibitive. A new type of PCU (Environmentally Smart Nitrogen, Agrium, Inc., Calgary, AB) is less costly than previous PCUs, but its effectiveness on potato production has not been extensively studied. A ...

Biosolids increase soil aggregation and protection of soil carbon five years after application on a crested wheatgrass pasture
Biosolids application to rangelands and pastures recycles nutrients and organic matter back to soils. The effects of biosolids (20 and 60 dry Mg ha–1) and N+P fertilizer on soil aggregate stability, bulk density, aeration porosity, and total C and N of stable aggregates were evaluated 4 and 5 yr after surface application to a crested wheatgrass [Agropyron cristatum (L.) Gaertn.] pasture in the ...

Fertiliser taxation and regulation of nonpoint water pollution: a critical analysis based on European experiences
In Europe, the effectiveness of current forms of control of nonpoint nitrogen pollution is considered to be weak. This assessment highlights the need to introduce more efficient modes of regulation. Many economists recommend a simple tax based on known polluting factors, for example a tax on purchases of mineral fertilisers. In addition to its simplicity of application and low information cost, ...
