Abstract:
The integrated use of organic and mineral fertilizers is a practical and good way to preserve and sustain soil fertility, which results in increased availability of nutrients in the soil and their absorption by plants, thus increasing crop productivity. Due to the fixation of potassium in the soil, it is necessary to work to increase the vitality of agricultural soil by adding fertilizers. Organic potassium is an important means of increasing the availability of macro- and micro-nutrients.

Using peat soils for agricultural purposes is challenged by low fertilizer efficiency, especially potassium chloride (KCl). On the other hand, zeolite is a potential material to produce slow-release fertilizers to improve fertilizer efficiency. This study aims to evaluate and compare potassium leaching from a conventional potassium fertilizer, KCl, and a zeolite-based potassium fertilizer, ZEKA, on peat soil columns. The ZEKA fertilizer was produced using two different zeolite particle sizes: coarse zeolite (ZC) and fine zeolite (ZF). The K leached from the fertilizers was measured in a peat s

Abstract:
Potassium is a macro nutrient element that is needed by plants. Potassium plays a role in plant metabolism, maintains turgor, and forms stronger stems. Sadly. Potassium is easily lost through washing because it is easily soluble in water. This is what triggers plants to often experience a lack of potassium. Efficiency in the use of potassium fertilizers can be increased through the formulation of fertilizers made in the form of slow release (Slow Release Fertilizer), namely by controlling the solubility of the substance in water through fertilizer coating.

Willamette spider mite prefers cooler climates and feeds by puncturing the plant leaf tissue; therefore removing plant nutrients in the early stages of plant growth.

Moreover, application of potassium fertilizer to the soil surface increased the amount of exchangeable potassium in the soil, thereby suppressing absorption of radiocesium by newly planted Konara oak trees.

Abstract:
On sod-podzolic medium-loamy soils of the Central Non-Chernozem region of Russia with an average availability of mobile forms of phosphorus and an average close to low potassium content, high efficiency of using potash fertilizer together with phosphorus on birdsfoot trefoil seed crops was established. Effective doses of phosphorus-potassium fertilizers, providing an increase in seed yield in the first year by 42–47% and, according to the aftereffect, in the second year by 17–33%, are the application of P30–60K90–120.&#x0D; Keywords: Birdsfoot trefoil (Lotus corniculatus L.), seed herbage, pho

Abstract:
Enhanced forest growth may respond to demand of woody resources and contribute to the climate change mitigation. Forest soil treatment with fertilizers, as well as drainage and thinning enhance forest growth. The analysis of needles is an established method in forest science to identify the nutrient status in the forest stand and need for forest soil enrichment with fertilizers. The aim of this research is to estimate the efficiency of forest soil enrichment with wood ash and ammonium nitrate in order to eliminate nutrient deficiency in forest stands. Forest soil was enriched with wood ash fer

Abstract:
Due to the agricultural intensification in Sri Lanka, there is a high demand for potassium (K)-fertilizer inputs. However, in the Sri Lankan geological setting, the presence of major potash sources is minimum though the K- bearing minerals and rocks are abundant. Therefore, exploration of K-bearing mineral deposits is essential to cater the demand of K-fertilizer in the country. In this regard, this research is focused on investigating the K-bearing minerals and rocks in Sri Lankan geological terrain which can be used as K-fertilizers directly or as alternatives for currently available K-ferti

Abstract:
Chemical fertilizers are a quick way to increase nutrients in the soil, but their use is economically costly and dangerous for the environment. Plant Growth Promoting Bacteria (PGPB) are able to increase the bioavailability of fertilizers through biological nitrogen (N) fixation, as well as potassium (K), phosphorus (P), and zinc (Zn) solubilization. The enhanced amount of soluble macro- and microelements in the close proximity of soil-root interface increases the fertilizer use efficiency ~ by 20-40 %.

The long term goal of this research project was to improve control efficiency of Alternaria diseases while reducing fungicide use, by integration of chemical and non-chemical factors. Non-chemical factors were genotype resistance, age-related resistance and fertilizers. The Specific objectives were: 1) To quantify changes in resistance among genotypes and over time in terms of disease development and specific phases of the disease cycle; 2) To quantify the effects of fertilizers applied to the foliage alone, or in combination with a fungicide, on disease development; 3) To quantify the relativ
