pH Minus / Efficiency Plus
In order for pesticides and fertilizers used in agriculture to be effective, the pH level is required to be below 7. pH values above 7 interfere with the intake of plant nutrients and more importantly, most pesticides will not work. As Olimpum, we offer you a solution. Thanks to ''Oligro pH Minus'', you can reduce the pH of the water and get maximum efficiency from pesticides and fertilizers. ...

Accounting for adaptation in assessing impact of climatic variations on crop yields: an empirical study of Arizona
The goal of this paper is to analyze the impacts of climatic variation around current normals on crop yields and explore corresponding adaptation effects in Arizona, using a unique panel data. The empirical results suggest that both fertilizer use and irrigation are important adaptations to climate change in crop production. Fertilizer use has a positive impact on crop yields as expected. ...

Many Countries Reaching Diminishing Returns in Fertilizer Use
When German chemist Justus von Liebig demonstrated in 1847 that the major nutrients that plants removed from the soil could be applied in mineral form, he set the stage for the development of the fertilizer industry and a huge jump in world food production a century later. Growth in food production during the nineteenth century came primarily from expanding cultivated area. It was not until the ...

Performance of an optimized nutrient management system for double-cropped wheat-maize rotations in North-Central China
Overapplication of N and P and insufficient supply of K are considered primary reasons for restriction of yield improvement in the North China Plain. Optimized nutrient management practices based on soil testing and yield targets have been developed. Other large scale field experiments have indicated that additional improvement for yield and nutrient use benefits is needed. The objective of this ...

Nitrogen recovery from source-separated human urine using clinoptilolite and preliminary results of its use as fertilizer
The use of source separated human urine as fertilizer is one of the major suggestions of the new sanitation concept ECOSAN. Urine is rich in nitrogen, phosphorus and potassium which act as plant nutrients, however its salinity is high for agricultural and landscape purposes. Moreover, characteristics change significantly throughout storage where salinity increases to higher values as the ...

Regulating fertilizer applications in agriculture for healthier crops & environment
Farm Fertilizer - A Double-Edged Sword The excessive use of fertilizers is one of the main causes of the environmental impact of industrial agriculture. The notion that more is better has caused more harm than good to farming, as well as the environment. Therefore, using the right amount of fertilizers is considered an important part of farm management. To this end, there has been a lot of ...

Influence of urea fertilizer placement on nitrous oxide production from a silt loam soil
Received for publication April 8, 2009. Urea placement in band or nests has been shown to enhance N use efficiency, but limited work has been done to assess its affect on N2O emissions. This study compared N2O emissions from urea prills applied to an Amsterdam silt loam (fine-silty, mixed, superactive, frigid Typic Haplustolls) using broadcast, band, and nest placements. Experiments were ...

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 ...

Necessity of the development of new organic fertilizer equipment
1. The necessity of developing new organic fertilizer. Fertilizer is one of the decisive factors for the high yield and quality of grain. The use of fertilizer has made a great contribution to the increase of crop production and the alleviation of food shortage. Fertilizer plays a very important role. In the past, the fertilizers used by people were relatively single, lacking fertilizers for ...

Rice growth, grain yield, and floodwater nutrient dynamics as affected by nutrient placement method and rate
The loss of major nutrients can be high in rice (Oryza sativa L.) fields, particularly rainfed rice, where water flowing from field to field during periods of high rainfall not only reduces the nutrient use efficiencies but also has the potential for environmental degradation. We examined the influence of deep point placement of N, P, and K briquettes compared to broadcast incorporation of N, P, ...

Ammonia sanitization of blackwater for safe use as fertilizer
Source-separated blackwater from low-flush toilets contains plant-available nutrients and can be used as a fertilizer. The aim of the study was to evaluate the impact on pathogen inactivation when treating blackwater with urea and/or lime. Blackwater was spiked with Salmonella typhimurium, Escherichia coli O157, Enterococcus faecalis, and Ascaris suum eggs, and treated with urea and/or lime in ...

Grain legumes in northern great plains
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 ...

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, ...

Sound Advice: Meeting Corn`s Nutrient Demands
In this edition of Sound Advice, Will Llewellyn, Sales Agronomist, shares his insights on how growers can meet corn’s nutrient demand all season long. Early in the crop’s life, nutrient needs increase slowly, until corn reaches the V10 to V14 window of peak nutrient demand. By the end of that window, much of the fertilizer applied since last fall has run its course. Fertilizer ...

How to Use Organic Fertilizer Equipment to Produce Fertilizer Suitable for Tomatoes
The application of chemical fertilizers in agricultural production can increase the yield of crops, but it will cause soil compaction, the quality of agricultural products will decline, and the nitrate content in fruits and vegetables will be too high. Bio-organic fertilizers are increasingly used in agricultural production. The organic fertilizer production equipment can combine organic matter ...

How to use organic fertilizer equipment to improve soil environment
Soil fertility has a great impact on crop yield and economic benefits. Soil fertility has declined and harvest has decreased, resulting in agricultural losses. Huaqiang equipment factory provides a complete set of professional organic fertilizer production equipment to help improve the agricultural soil environment. Three main reasons for the decline of soil fertility 1. The local land ...

Prospect and production of coated controlled release fertilizer
Coated controlled release fertilizer The traditional chemical fertilizer, such as N or a certain proportion of N, P, K compound fertilizer, is coated with a special biological or chemical water soluble polymer film. Based on the characteristics of film thickness, particle radius, diffusion coefficient, nutrient composition and dissolution, the release rate and amount of fertilizer nutrient are ...

Humic Acid Factory - Case Study
Humic acids or humus are black or dark brown substances formed by plant or animal residues that are partially or completely decayed. Humus is a substance that facilitates the uptake of fertilizers. Today, the increasing use of chemical fertilizers causes the humus in our land to be rapidly depleted. In order to solve this problem, more and more humic substances (humic acid and fulvic acid) are ...
