Nutrient acquisition and yield response of Barley exposed to salt stress under different levels of potassium nutrition
Abstract: A greenhouse experiment was carried out in 2002 at Jordan University of Science and Technology, Agricultural Experiment Station to examine the effect of potassium fertilization on the response of barley (Hordeum vullgare L.) to different soil salinity levels. Five levels of potassium (0, 0.2, 0.4, 0.6, and 0.8 g K per pot as KCl) and two salt levels (0.75 and 13 ds/m) were investigated ...

Rate and timing of potassium fertilization and fungicide influence rice yield and stem rot
Potassium deficient rice (Oryza sativa L.) is susceptible to diseases including stem rot (Sclerotium oryzae Catt.). Knowledge of how to manage K deficiency and the increased disease susceptibility is necessary to reduce rice yield losses. Our objectives were to determine the influence of K rate, application time, and azoxystrobin fungicide on grain yield and stem rot index (SRI) of rice grown on ...

From animal manure to artificial fertilizer and clean water - Case Study
Nijhuis Industries uses GENIAAL to convert raw manure or digestate into biobased phosphate, nitrogen and potassium fertilizer and clean water. GENIAAL is based on the production of valuable biobased fertilizers from raw manure and digestate and will therefore make an important contribution to solving the manure and phosphate surplus in the Netherlands as a cost-effective, innovative and ...

Main advantages and disadvantages of granulation process and technology of potash fertilizer
The potassium fertilizer is fed into the disc granulator, so that the material gradually piles up by itself until it reaches the required particle size. When the raw materials are piled up on the disc, the binder can be added to support the agglomeration of the materials. Since water will be added to the disc during granulation, additional drying process is required for the fertilizer production ...

Impact of long-term phosphorus and potassium fertilization on alfalfa nutritive value–yield relationships
Phosphorus (P) and potassium (K) increase alfalfa (Medicago sativa L.) yield, but little information is available on how forage nutritive value is affected by P and K fertilization. The objective of this study was to investigate the effect of long-term P and K fertilization on alfalfa yield–forage nutritive value relationships. A factorial experiment with four P and five K treatments was ...

Burn it no more!
The other day I came across an old news article from 2008 about a Dutch energy plant that burns 485,000 tons of poultry litter each year, converting it into renewable electricity. Wow, I thought. That is an old-fashioned way of getting rid of poultry litter – they must be releasing some 14,550 tons nitrogen gas into the atmosphere. All this to produce 270,000 MWh of electricity, 890,000 MWh ...

Why organic fertilizer equipment is suitable for small investment
In agricultural production, in order to achieve the increase of crop production, people do not hesitate to pour a large number of chemical fertilizer into the farmland. More and more nitrogen, urea and nitrogen, phosphorus, potassium compound fertilizer are used, and the concentration is higher and higher. Although this has kept the effect of increasing production to a certain extent, the ...

Difference between organic fertilizer and chemical fertilizer
What is chemical fertilizer Chemical fertilizers are quick acting and exist in many forms, such as liquid and particle. Chemical fertilizers are water-soluble, and plants can immediately absorb nutrients. Although this provides a fast nutrient and fast greening, it will not last. Only organic fertilizer can maintain plant growth all the time. Chemical fertilizer can promote plant growth rapidly, ...

Field trial carried out in the ebro valley, Spain case study
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 ...

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 ...
