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.Đọc thêm -
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.Đọc thêm -
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.Đọc thêm -
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.Đọc thêm -
Relationship Between Fertilizer & Plant Stretching
The goal of every grower is to produce high quality plants. One of the characteristics of a high quality plant is compact growth with good branching. Plants with these characteristics are stronger and able to withstand shipping and environmental stress. Growth regulators are often used to produce this desired growth, but fertilizer also has an impact on plant stretching and size.The three main attributes associated with plant stretch from fertilizer are: fertilizer application rate, nitrogen forms and phosphorus.Đọc thêm -

Potassium Fertilizers: Muriate of Potash or Sulfate of Potash?
Potassium (K) is an essential nutrient required by plants in large quantities. Potassium does not become part of the many complex organic molecules in the plant. It moves and performs many of its functions as a free ion, such as regulating plant water pressure, activating enzymes, balancing electrical charges, transporting sugars and starches, and more.1 Potassium fertilizers are mined from a variety of geologic potassium salt deposits around the world, some of the richest are in the Canadian province of Saskatchewan. The salts are processed to remove impurities and converted to a variety of fertilizers. Two of the most popular potassium fertilizers derived from these salt deposits are potassium chloride and potassium sulfate. The term “potash” is a general term that is often used to refer to a variety of potassium fertilizer salts or sometimes more specifically to potassium chloride, the most widely used potassium fertilizer. Potassium chloride is referred to as “muriate (meaning chloride) of potash” or MOP, while potassium sulfate is sometimes called “sulfate of potash” or SOP.2,3Đọc thêm -
The Importance of Potassium in Fertilizer
Losing a lawn to the stress of summer heat or the cold of winter can be very frustrating to homeowners and lawn care professionals alike. As a professional, you might spend hours tending to your customers’ lawns just for them to die off during a stressful season. As a turf-care professional, the overall goal should be lawn (and soil) health since a healthy lawn will give you the color, growth, and durability your customers are looking for. Contrary to what some people might think, the green color of the lawn in the summer or winter does not necessarily guarantee the health of the lawn. The health and success of the lawn during a stressful season is more dependent on less visible factors, like its access to and use of potassium, than many landscapers consider.Đọc thêm -
ROLES OF POTASSIUM IN PLANTS
Potassium is an essential plant nutrient, one of the three macro-elements required by plants in relatively large quantities – nitrogen, potassium and phosphorus (NPK). What are the roles of potassium in plants? How does potassium affect plant performance?Potassium enhances crop yields and quality in different ways. For example, it increases sugar content in fruits, size of vegetable crop fruits, protein content in cereals, helps maintaining longer shelf life, improves plants’ resistance to diseases and to drought and more.Đọc thêm
