Krill as a Source of Minerals - Case Study
Krill has a low content of ash making ideal for fresh water feeds. It is lower in content of phosphorus than other marine based meals such as shrimp or fish meal. Its calcium/phosphorus ratio is near to 1,5:1 which favors the absorption of both minerals, and it is significantly lower compared to fish or crustacean meals (3 or ...

Characteristics of NPK fertilizer production by double roller granulator
The main characteristics of NPK fertilizer production by counter roll pelletizing equipment are as follows: Processing compound fertilizer containing a certain proportion of nitrate nitrogen. Nitrate nitrogen is widely used due to its high temperature and humidity, but it has strong hygroscopicity, and it will be deliquescence into mud under high temperature and humidity, which makes the ...

What are the advantages of using rabbit manure as organic fertilizer?
Nutrient content of rabbit feces Rabbit manure is a kind of high efficient organic fertilizer, the content of nitrogen, phosphorus and potassium is significantly higher than other animal manure. The nitrogen content of rabbit manure is 1.53 times of chicken manure, 3.29 times of sheep manure, 3.83 times of pig manure, the phosphorus content is 2.88 times of chicken manure, 4.6 times of sheep ...

Difference between the production machines of organic fertilizer and compound fertilizer
The internal quality of organic fertilizer mainly depends on raw material fermentation and product formula. The key factors affecting the fermentation of organic fertilizer production process are: microorganism, carbon nitrogen ratio, carbon phosphorus ratio, water content, pH value, aeration control. If one factor is not properly controlled, the whole fermentation will be affected, resulting in ...

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 ...

Enhancing Foliage Color of Ornamental Cabbage and Kale with LEDs
Enhancing Foliage Color of Ornamental Cabbage and Kale with Prior-to-Shipping Light and Temperature Treatments in Coolers Introduction Ornamental flowering cabbage and kale (Brassica oleracea var. acephala) is a bedding plant that is typically produced outdoors in the late summer and early fall. It is popular due to its vibrant and intense purple, white, and pink foliage colors that are ...

New study finds recycled phosphorus could fertilize 100 percent of U.S. corn
The world has a problem. A phosphorus problem. Needed to fertilize crops, the bulk of phosphorus comes from nonrenewable phosphate rock. While China mines the most — producing almost half the world’s phosphorus — Morocco alone controls three-fourths of global phosphate rock reserves. Year by year those global reserves dwindle, leaving phosphate rock that’s ever lower in ...

Assessing long-term water quality impacts of reducing phosphorus fertilizer in a US suburban watershed
Phosphorus run-off from urban lawn care is a significant water quality concern in many US suburban communities. Many state and municipal governments in the USA adopt urban fertilizer laws or ordinances that prohibit the use of phosphorus-containing lawn fertilizers. This study assesses the long-term water-quality impacts of two phosphorus-reduction scenarios in a suburban watershed in Central ...

Intercropping different varieties of radish can increase cadmium accumulation in radish
Genetic diversity has supplied effective ways to improve crop yields and disease resistance. Therefore, we may be able to reduce crop uptake of heavy metals by collecting germplasm resources. In this study, cadmium accumulation and nutrients in radish was investigated by intercropping three genotypes (red, green, and white radish) in different combinations. Both pot and field experiments ...

Impact of imidacloprid on Daphnia magna under different food quality regimes
Aquatic ecosystems are characterized by fluctuating conditions that have direct effects on aquatic communities, but also indirect influences such as changing the toxicity of chemicals. Since the effect of food quality on pesticide toxicity has rarely been studied, in the current experiment Daphnia magna juveniles supplied with four different food quality levels were exposed to a range of ...

Critical source area management of agricultural phosphorus: experiences, challenges and opportunities
The concept of critical source areas of phosphorus (P) loss produced by coinciding source and transport factors has been studied since the mid 1990s. It is widely recognized that identification of such areas has led to targeting of management strategies and conservation practices that more effectively mitigate P transfers from agricultural landscapes to surface waters. Such was the purpose of P ...

A review of the phosphorus content of dry cereal and legume crops of the world
When food scarcity increases, instability in society increases. The majority of food consumed is from cereals and legumes. Phosphorus is essential for crop plant growth and soils are depleted as this element is removed from crop lands with harvested grains/seeds. To sustain yields, inputs of nutrients are required to balance losses. On global and continental/regional bases, we assembled nine ...

Phosphorus runoff from turfgrass as affected by phosphorus fertilization and clipping management
Received for publication December 8, 2008. Phosphorus enrichment of surface water is a concern in many urban watersheds. A 3-yr study on a silt loam soil with 5% slope and high soil test P (27 mg kg–1 Bray P1) was conducted to evaluate P fertilization and clipping management effects on P runoff from turfgrass (Poa pratensis L.) under frozen and nonfrozen conditions. Four fertilizer treatments ...

Phosphorus distribution in untreated and composted solid fractions from slurry separation
Received for publication May 7, 2009. The distribution of phosphorus (P) (water-soluble inorganic P [Pi], acid-soluble Pi, and residual P) was determined in 40 samples of solids from solid–liquid separated slurry. These were collected from separation plants using different technologies, separating by simple mechanical means, by flocculation as pre-treatment before mechanical separation or by ...

Enhancing phosphorus phytoremedation potential of two warm-season perennial grasses with nitrogen fertilization
Phytoremediation or use of plants to extract soil nutrients is a practice used to ameliorate the impacts of excessive soil nutrients. Pensacola bahiagrass (Paspalum notatum Flügge) and ‘Floralta’ limpograss [Hemarthria altissima (Poir.) Stapf & Hubb] were grown in a P-impacted Immokalee fine sand (Mehlich-1 P 30 mg P kg–1) to evaluate increasing N levels on dry matter yield (DMY), forage P ...

Nitrogen fertilization effect on phosphorus remediation potential of three perennial warm-season forages
Warm-season C4 grasses are capable of removing excess soil nutrients because of their high yield potential and nutrient uptake efficiency. Bahiagrass (Paspalum notatum Flügge), limpograss [Hemarthria altissima (Poir.) Stapf & Hubb], and stargrass (Cynodon nlemfuensis Vanderyst), three commonly used pasture grasses in South-Central Florida, were grown to examine the effect of increasing N ...
