Chemicals and fertilizers

Proper fertilization is critical to the healthy and vigorous growth of a lawn. While general fertility guidelines can aid in maintaining high quality turfgrass, even the best recommendations are of little value if one cannot accurately apply the fertilizer recommended. In order to intelligently purchase and apply turfgrass fertilizers, one must be able to read and understand a fertilizer label. Many different types of fertilizer are available for use on turfgrass. Complete fertilizers contain nitrogen (N), phosphorous (P) and potassium (K) and are widely used for turfgrass fertilization. For certain situations, incomplete fertilizers containing some combination of N, P and K, but not all three elements, may be the best choice. Every fertilizer material, whether complete or incomplete, must carry a label stating the guaranteed analysis of the material. The exact label information may vary from state to state, as no uniform countrywide regulations exist; the manufacturer is, however, usu

Knowing Your Lawn Fertilizer for Grass Care Fertilizer is basically food for your grass. The common misconception about plant food is that they are made of chemicals manufactured in the laboratory. But actually, the basic ingredients of good fertilizer can be found in the environment—decomposing organic matter. But, combining this organic matter with three important elements is the key to a beautiful and lush looking lawn. The 3 Key Elements (1) Nitrogen- This is the most important element among the three when it comes to creating the best lawn fertilizer. Nitrogen gives your grass its healthy green color. It also makes each blade of grass strong and sturdy so it is less prone to breakage. Strong grasses have greater ability to fight off insect damage and harsh outside conditions like cold and dry weather. (2) Potassium- It works with the nitrogen to make roots and foliage stronger. Giving your lawn good foundation will help it resist from drought, tearing, and extreme weather. Potassi

regurdless of location, the fertilizer prices are on the top of the list of everyone’s concerns. In 2009, except for land charges (cash rest or land payments) the majority of the input dollars will be used to purchase fertilizer. Growers and the ag-professionals who advise them are interested in trimming fertilizer costs and are looking for any type of help that they can find. Some thoughts on cost-cutting are described in the paragraphs that follow. DON’T USE CROP REMOVAL AS A GUIDE: Recently, print and radio or TV advertising seems to be stressing the amount of P and K removed from the soil by high-yielding crops. This advertising implies that it is a mistake to apply less than the crop removes and, subsequently, yields will suffer. Research in Minnesota has shown that this implicattion is not true. In fact, the use of crop removal as a basis for making decisions about rates of phosphate and potash to apply will lead to the most expensive fertilizer program. You can make two mi

INTRODUCTION: In recent years soluble fertilizers otherwise known as foliar fertilizers were introduced in A.P in the names of Polyfeed and Multi ‘K’ Polyfeed contains 19 : 19 : 19 NPK with 6 micro-nutrients like iron, manganese, boron, zinc, copper and molybdenum, while multi K contains 13 : 0: 46 NPK. These fertilizers provide nutrients to the plant by foliar application as these fertilizers are completely soluble in water. These fertilizers have no other impurities like sodium and chloride and they are 100 % nutrients and these nutrients are easily absorbed through the leaves. In certain occasions like prolonged drought, there is no scope to apply fertilizers to the soil for want of moisture. Like wise in flooded conditions due to continuous rains fertilizers could not be applied to the soil. In such special circumstances these soluble fertilizers are must to protect the cro

The Alkali Metals 3 Li 6.941 11 Na 22.99 19 K 39.10 37 Rb 85.47 55 Cs 132.9 87 Fr (223) This page contains brief profiles and pictures of each of the alkali metals, and the characteristic flame colors for their compounds. More information can be found via Internet. Li Lithium is the lightest of all metals and is named from the Greek work for stone ( lithos ). It is the first member of the Alkali Metal family. It is less dense than water (with which it reacts) and forms a black oxide in contact with air. Lithium was discovered in 1817 by Johan August Arfwedson but not isolated until some time later by W.T. Brande and Sir Humphry Davy. In its mineral forms it accounts for only 0.0007% of the earth's crust. It compounds are used in certain kinds of glass and porcelain products. More recently lithium has become important in dry-cell batteries and nuclear reactors. Some compounds of lithium have been used to treat manic depre

hough agricultural revolution has led to unbelievable yields and crop productions but the means which have derived all these increments seem to hamper the fertility of soil. The harsh chemical have started registering their harmful side effects on the soils. Today what each farmer is looking forward to is a proper solution to the agricultural problems without compromising on the yields. It is an universally acknowledged fact that organic fertilization methods are more environmental friendly and fetch slower but steady results. Today when the world is advancing so fast in every aspect, how can the life supporting area can be ignored? Today the use of fertilizers is one of the greatest innovations of the agricultural revolution.

Fertilizer application methods. There are three main application methods for liquid fertilizers Direct soil application, mechanical spread by broadcasting or deep soil placement by injection. Fertigation: Injecting the fertilizer solution with the irrigation water. Foliar spray application Principles of Fertigation This is the most common method for the application of liquid fertilizer solutions and disolved solid water soluble fertilizers. The concentrated fertilizer solution is injected into the irrigation water, mixes with it and enters the soil during irrigation. This is the most efficient method for the fertilization of irrigated crops, specially for those irrigated with drippers, micro- jets and micro- sprinklers. A range of injection accessories is available for fertigation. How to prepare a fertilizer solution from a solid, water soluble fertilizer. Gatit fertilizers should be dissolved in three volumes of water according to the following procedure. For example:

Organic gardening involves a system that centers around healthy soil - a mixture of sand, clay, silt, and decomposed organic material (humus). But even when the soil is well-balanced and healthy, plants benefit from additions of specifically formulated organic fertilizers. You can buy prepared organic fertilizers, or blend individual fertilizer ingredients for specific purposes, such has high nitrogen blends for leafy greens or high potassium blends for root crops. Since the following organic fertilizer recipes all involve dry ingredients, they can be blended ahead of time and stored in labeled plastic containers with lids. Most gardening centers will have the individual ingredients, but if you can't buy them locally, they are available from online sources, such as Whitney Farms, which sells only organic products. For all of the following recipes, make any amount using the volume ratios given. Use anything from a yogurt container to a lemonade pitcher as a scoop. Each full scoop eq

1. What is biofertilizer? Biofertilizers are ready to use live formulates of such beneficial microorganisms which on application to seed, root or soil mobilize the availability of nutrients by their biological activity in particular, and help build up the micro-flora and in turn the soil health in general. 2. Why should we use biofertilizers? With the introduction of green revolution technologies the modern agriculture is getting more and more dependent upon the steady supply of synthetic inputs (mainly fertilizers), which are products of fossil fuel (coal+ petroleum). Adverse effects are being noticed due to the excessive and imbalanced use of these synthetic inputs. This situation has lead to identifying harmless inputs like biofertilizers. Use of such natural products like biofertilizers in crop cultivation will help in safeguarding the soil health and also the quality of crop products. 3. What are the benefits from using biofertilizers? Increase crop yield by 20-30%.

Forms For Concrete Work General To use concrete in making any object, it is necessary that the material, while in a plastic state, be confined in e form or mold which has an interior surface and shape corresponding to that of the object which is to be made. Therefore forms or molds are the receptacles in which a concrete mixture is placed immediately after mixing so that when hardened the concrete will assume the shape desired or intended. Forms for concrete steps. Care should be taken to have the ground well compacted where steps are to rest. The side walls, or ramps, can be made first or last as desired. A 1:2:4 concrete mixture should be used throughout. The concrete should be wood floated on the step treads instead of finished with a steel trowel, Using a wood float will give a surface that will provide a good foothold. Types Of Forms Forms for concrete may be made wholly of wood, or of wood metal lined, or wholly of metal, or in some cases of plaster of Paris.

Organic fertiliser is obtained from various chemicals. It contains range of nutrients at different ratio, making it effective for plants. These are easily absorbed in plant systems. Organic Fertiliser are available as solid spray dried powder or liquid solution. This powder if fully soluble in water and can be dissolved in water to prepare formulation of required concentration HUMIC ACID: Application of humic acids has several benefits and agriculturists all over the world are accepting humic acids as an integral part of their fertilizer program. Biochemical active and plant responsive humic substance are naturally occurring humic acids. They can be applied directly to the plant foliage in liquid form or to the soil in the form of granules alone or as fertilizer mix. Benefits of Proper Application of Humic Acid increase soil fertility, Increase humus contents, Effectively chelates meta

Overview Potassium is one of the alkali metals. The alkali metals are the elements that make up Group 1 (IA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. The alkali metals also include lithium, sodium, rubidium, cesium, and francium. They are among the most active metals. Potassium is so active that it never occurs free in nature. It always occurs in compounds, combined with other elements. It was first prepared in pure form in 1807 by English chemist Sir Humphry Davy (1778-1829). Davy used a new method of isolating elements that he had invented, electrolysis. In electrolysis, an electric current is passed through a molten (melted) compound. The electrical current breaks the compound into its elements. (See sidebar on Davy in the
