NPK: What is it and why is it so important?
Romke Postma is working as a senior project manager and soil fertility expert at NMI-Agro, a soil research agency working closely with AgroCares. SoilCares (now part of AgroCares) recently launched the SoilCares Manager app, which enables advisors to test the NPK levels in soil. But what is NPK? And why is it so important? In this new blog Romke explains the importance of these nutrients for plants and crops.Leer más -
Potassium for crop production
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.Leer más -
Why Are Nitrogen, Phosphorus, and Potassium in Plant Fertilizer?
Look at the label on any fertilizer package, and you'll see three numbers separated by dashes, which correspond to the amounts of primary nutrients in the product. For example, one with three of the same number, 4-4-4, is called a "balanced" fertilizer because it has equal amounts of the Big 3 N-P-K (always shown in that order). A container of tomato food ($12, The Home Depot) might be labeled 2-5-3, which indicates higher amounts of P and less N and K. Why do these levels matter, and what do nitrogen, phosphorus, and potassium do for plants anyway? Here's what you need to know.Leer más -
What is NPK Fertilizer? And What Does N-P-K Do for Plants?
When my husband and I moved into our new house, the blank slate backyard became my project.By spring, I noticed the leaves on some bushes turning yellow. You’d think it’s a nitrogen deficiency, right?But after some serious digging (pun intended!), I discovered it was iron chlorosis (a lack of available iron) NOT a lack of nitrogen, causing the leaves to turn yellow.Leer más -
The role of N，P，K fertilizers and the harm of excessive use
The application of fertilizers is not as good as possible, and excessive use of chemical fertilizers will cause many harms. Let's analyze in detail the effect of a large amount of nitrogen, phosphorus and potassium fertilizers and what harm will be caused by excessive use.Leer más -
The ABCs of NPK: A fertilizer guide
Get a soil test. Find out your soil's pH and follow any recommendations from the testing lab.Calculate the square footage of your garden. Multiply length by width.Use the soil recommendations and your square footage to decide what type of fertilizer is required and how much you need for your area.Decide what fertilizer you need for what you want to grow. Buy enough fertilizer to treat the area.Read the bag or bottle thoroughly before applying fertilizer. Apply at recommended rates or less; do not use more.Leer más -
Influence of Nutrient (NPK) Factors
The purpose of this study was to investigate the effects of nutrients (NPK) on the growth indexes (plant height, stem and leaf fresh weight, fibrous root fresh weight, and rhizome fresh weight), pharmacodynamic components (atractylenolide II, β-eudesmol, atractylodin, and atractylon), key enzymes (ACC, HMGR, and FPPS), and the genes of A. chinensis. Under different NPK combinations, the T6 (N2P3K1) scheme notably promoted the yield and volatile oil content of A. chinensis. Therefore, we believe that the process of planting A. chinensis involves, “heavy application of P fertilizer, and appropriate application of N and K fertilizer.” In addition, we noticed that the synthesis of polyacetylene atractylodin was closely related to ACC; furthermore, FPPS had an important regulatory effect on the synthesis of sesquiterpenes atractylenolide II, β-eudesmol, and atractylon. At the same time, the T6 fertilization program notably improved the key enzymes ACC and FPPS activity and gene expression. In summary, reasonable NPK administration can both effectively promote the growth of the medicinal parts of A. chinensis, and also promote the accumulation of medicinal ingredients by regulating the expression of key enzymes and genes in the synthesis pathway.Leer más -
What Do the NPK and Numbers of Fertilizer Mean?
Like many other additives, peat materials contain little or no nutrients. It is almost always important to fertilize peat products to ensure good plant growth. Fertilizer with a certain formula is usually used in the production of substrates. Commonly used are NPK 14-16-18, NPK 12-14-24 and NPK 15-10-20. All these fertilizers contain major elements as well as trace elements. It is important for the plant to have both major and trace elements available from the start. It should not be forgotten that these fertilizers are active only in the first weeks of cultivation. Soon, the grower will have to start fertilize when the culture lasts longer.Leer más -
NPK Fertilisers
NPK fertilisers play a pivotal role in modern agriculture, enabling the enhancement of plant growth and optimising crop yields. Comprised of three essential nutrients—nitrogen (N), phosphorus (P), and potassium (K)—these fertilisers are crucial for the health and productivity of various crops. Understanding the chemical composition, application methods, and environmental impact associated with these inputs is essential for effective and sustainable agricultural practices. This comprehensive guide delves into the basics, uses, production processes, key elements, and ecological considerations of NPK fertilisers, providing valuable insights for both seasoned farmers and those new to the field of agronomy.Leer más
