Ferrous Ammonium Sulphate is also called Mohr’s salt a light green color sand like crystalline solid. It is a hazardous substance and preparation of ferrous ammonium sulfate is carried out from equimolar mixture of hydrated ferrous sulphate and ammonium sulphate in water; containing a little of sulphuric acid.

It’s the earth’s cultivated cropland that keeps humanity alive and thriving. Plants provide food, fiber, housing and a host of other benefits, and fertilizer plays a key role in this process. As the world population is expected to exceed 9 billion by 2050, fertilizer will be needed more than ever to boost crop production to keep people fed and healthy.All growing plants need 17 essential elements to grow to their full genetic potential. Of these 17, 14 are absorbed by plants through the soil, while the remaining three come from air and water.Generations of soil science have yielded knowledge of how to test nutrient levels in soil, how plants take them up and how best to replace those nutrients after harvest. That’s where fertilizer comes in.

The use and purpose of MKP was discussed in my previous article here. This time I will share on how I prepare the solution and how I measure the concentration of the foliar spray for my farm's durian trees foliar spray usage.

Ammonium sulfate is a chemical compound with the formula (NH4)2SO4. It is a white crystalline solid that is highly soluble in water. It is commonly used as a fertiliser to provide plants with nitrogen and sulfur. Ammonium sulfate is produced by the reaction of sulfuric acid and ammonia and is typically sold as a granulated powder. Ammonium sulfate is also used in the production of dyes and other chemicals.

Welcome to HUMICO, a leading manufacturer of organic fertilizers in China. With a diverse range of products, including amino acid, humic acid, NPK ball, seaweed extract, and more, we are dedicated to promoting sustainable and organic farming practices. Today, we'll delve deep into one of our flagship products - the potassium humate powder fertilizer.

This soluble humic acid powder is a concentrated source of humic acids which makes a liquid solution containing up to 12% Humic Acid (by weight).

Potassium humate is a highly effective organic fertilizer, because humic acid is a high active agent, can increase available potassium in soil, reduce the loss and fixation of potassium, increase crop potassium absorption and utilization,also can hold the nitrogen and slow release,unclock the phosphorus inside the soil ,chelate the micro elements, improve the soil structure to increase its water holding capability and create good environment for microbial group ,which will also help to improve the soil structure.Accordingly the soil fertility will be greatly increased and increased plants growth and harvest and its fruits quality.

Improves soil structure thus to increases water holding capacity and soil cation exchange capacity (CEC) to increase soil fertility.

Potassium humate has important uses in agriculture. Fulvic acid, black humic acid and brown humic acid are collectively called humic acid. In which fulvic acid has small molecular weight and high active, easily abserbed by plants and quick effect.

Sustainability over the long term. Many changes observed in the environment are long term, occurring slowly over time. Organic agriculture considers the medium- and long-term effect of agricultural interventions on the agro-ecosystem. It aims to produce food while establishing an ecological balance to prevent soil fertility or pest problems. Organic agriculture takes a proactive approach as opposed to treating problems after they emerge.

Potassium (K) is an essential nutrient for plant growth. It’s classified as a macronutrient because plants take up large quantities of K during their life cycle.Minnesota soils can supply some K for crop production, but when the supply from the soil isn’t adequate, a fertilizer program must supply the K.Here, we’ll give you a basic understanding of K, including plants’ K nutrition, how it reacts in soils, its function in plants and its role in efficient crop production. In addition, you’ll find information about soil tests, K sources, predicting potash needs and effectively applying K to your fields.

Potassium (K) is an essential element for plant growth it is important to food crops. Potassium, often called potash, helps plants use water and resist drought and enhances fruits and vegetables.   If soluble Potassium is deficient in soil it can stunt growth and cause other symptomatic issues.  To overcome deficiencies Potassium is commonly applied to gardens, lawns and orchards as part of a balanced fertilizer.  In addition, Potassium promotes healthy green lawn grass.

Our results showed that M9T337 seedlings treated with the optimum K levels had (i) enhanced 13C accumulation and 13C transport from leaves to roots; (ii) increased root NO3– ion flow rate; (iii) relatively high N metabolic enzyme activities; (iv) up-regulated transcript levels of nitrate uptake genes (NRT1.1; NRT2.1); (v) enhanced 15N translocation from roots to leaves; (vi) higher 15NUE. In conclusion, optimum K levels can increase NUE by affecting root morphology and activity, the activity of enzymes involved in C and N metabolism, nitrate uptake genes, and nitrate transport.

Potassium (K) is one of 17 nutrients that are essential for plant growth. Like nitrogen (N) and phosphorus, it is a macronutrient because plants require large amounts of K. Depending on the crop, the K requirement can be nearly as high as the N requirement. The following table shows the amount of K used by selected crops. Unlike most nutrients, most K is retained in the straw, or stems of crops. This means that relatively little K is removed each year with seed harvest, but large amounts of K are removed with the harvest of straw, and forage or green feed crops.

Potassium (K) is one of the 17 essential nutrients required by plants for growth and reproduction. Like nitrogen (N) and phosphorus (P), potassium is classified as a macronutrient. The term “potash” refers to a group of potassium bearing minerals and salts. There are multiple potassium fertilizer sources, expressed in units of K₂O on fertilizer labels, such as muriate of potash (KCl), sulfate of potash (K₂SO₄), double sulfate of potash and magnesium (K₂SO₄ 2MgSO₄), and nitrate of potash (KNO₃).

Potassium deficiency in agricultural soils is a largely unrecognised but potentially significant threat to global food security if not addressed, say researchers.The lack of this key nutrient can inhibit plant growth and reduce crop yields. Farmers often spread potassium-rich fertilisers over their fields to replenish the depleted nutrient, but supply issues can inhibit its use and there are also questions about the environmental impact. The new study, published in Nature Food, finds that in many regions of the world, more potassium is being removed from agricultural soils through leaching or when crops are harvested. The authors from the UK Centre for Ecology & Hydrology (UKCEH), the University of Edinburgh, University College London and the Institute of Environmental Assessment and Water Research in Spain make a series of recommendations to tackle the issue.

Potassium is essential in nearly all processes needed to sustain plant growth and reproduction. Plants deficient in potassium are less resistant to drought, excess water, and high and low temperatures. They are also less resistant to pests, diseases and nematode attacks. Because potassium improves the overall health of growing plants and helps them fight against disease, it is known as the “quality” nutrient. Potassium affects quality factors such as size, shape, color and vigor of the seed or grain, and improves the fiber quality of cotton.

Some soils do not even build well using manganese sulfate. In a very few cases it has been necessary to apply the needed amount for two or three years in a row to reach the desired minimum level. In such cases, the use of ammonium sulfate as a nitrogen source may help, but generally the amounts used do not show much progress in building up soils deficient in manganese. A crop which can also help to increase manganese availability in the soil is rice.Just keep in mind that the primary elements, N-P-K, truly are primary in terms of getting enough nutrients there to grow the crop. But when any one of these three are over-applied, providing more than the soil can tolerate, those same elements can cause a whole new set of problems, not just for potatoes, but for all types of crops and growing plants.

Soils around the world are running low on potassium, a key nutrient needed for plants to grow. This ultimately means we may not be able to grow enough food for everyone.But it’s not too late: we have just published research identifying six things we must do to safeguard potassium supplies and food production.

Potassium (K) is a macronutrient for corn because the plant takes up large amounts throughout the growing season. While K is not used by the plant as a building block for organic compounds, it functions as an activator for many enzymes and metabolic pathways, including those for photosynthesis and protein and starch formation in grain. Potassium plays a role in the flow of water, nutrients, and carbohydrates within the plant. It plays a role in the regulation of stomata closing and opening, thus impacting the exchange of water and gases. Additionally, K is key for cell wall strength and cellulose production. Good K fertility is associated with strong cell walls that enhance disease resistance and the ability of the crop to maintain firm, healthy stalks (Table 1).
