ECOLOGICAL PEST MANAGEMENT

In organic farming systems pest control strategies are largely preventive, rather than reactive. Organic farming is not single method but rather a variety of techniques which are aimed at reducing costs, preserving the environment and protective human health by eliminating the toxic farm chemicals. Pest-insect, diseases causing pathogens, weeds and nematodes are estimated to cause an annual loss of about 33-35 percent of potential food production world wide.

Jump into Agricultural Business

If you have much interest on agriculture, you can jump into an agricultural business. But keep in mind that it’s a long term investment and you do not get rich right away. This business isn’t like the share business or, marketing business where you can make profit in a single day. In this business you must invest for few years for getting the rich amount.

Importance of Organic Agriculture

Now a day’s fertilization problem is one of the major problem in environment. Among the environmental problems is the continuous destruction of the soil because of excessive use of inorganic fertilizers which has resulted to soil infertility. An evidence to justify this fact is the gradual extinction of wild plants which were in the past, just sprout from the soil without human interventions. Another problem is the contamination of the water source and air because of excessive use of pesticides

Mushroom Growing Tips for Beginner

Growing mushrooms is probably the easiest thing you can do if you discouraged or afraid because you are new to mushroom growing. Mushroom developing is starting to become more common as personal chefs and restaurants are starting to create more dishes that include them. Mushrooms bring a unique flavor to a dish and can be good for your health. If you start mushroom developing you might just have started your first mushroom growing business without even knowing it.

BENEFICIAL EFFECTS OF MICROORGANISMS IN THE FIELD OF AGRICULTURE

Agriculture in a broad sense, is not an enterprise which leaves everything to nature without intervention. Rather it is a human activity in which the farmer attempts to integrate certain agroecological factors and production inputs for optimum crop and livestock production. Thus, it is reasonable to assume that farmers should be interested in ways and means of controlling beneficial soil microorganisms as an important component of the agricultural environment.

Crop Response to Soil Salinity

Excess soil salinity causes poor and spotty stands of crops, uneven and stunted growth and poor yields, the extent depending on the degree of salinity. The primary effect of excess salinity is that it renders less water available to plants although some is still present in the root zone. This is because the osmotic pressure of the soil solution increases as the salt concentration increases. Apart from the osmotic effect of salts in the soil solution, excessive concentration and absorption

Methods of Potassium Fertilizer Application

Annual Crops

Since potassium uptake depends primarily on root interception, placement of potassium fertilizers with or near the seed is usually the most effective method of application provided the rate of application is not greater than the seed can tolerate. If too much potassium or other fertilizer is placed with the seed, germination and emergence may be delayed or reduced.

Fate of Potassium in Soils

Three forms of K (unavailable, slowly available or fixed, readily available or exchangeable) exist in soils. A description of these forms and their relationship to each other is provided in the paragraphs that follow. The general relationships of these forms to each other are illustrated in following Figure:

BENEFICIAL EFFECTS OF MICROORGANISMS

Microorganisms or microbes are living things, such as bacteria, fungi, viruses, protozoa, microscopic algae, that are too small to be seen by naked eyes. Microorganisms can be both harmful and useful. Actually, the existence and functioning of microorganisms is crucial to a healthy environment. The benefits of microorganisms include:
