Green Manures

During the time of Green Revolution period, the use of chemical fertilizers assumed the center point, to increase the crop production. But the damage done to the soil by continued usage of the inorganic manures is felt now by everyone around the world.

The agricultural scientists and the soil specialists are driving home the point to the farming community to go in for the balanced use of chemical fertilizers along with the green manures. But it is pertinent to adhere to their advice as the production level is drastically coming down in many pockets of the world due to the indiscriminate use of the inorganic manure.

The traditional leguminous green manures grown in the field and ploughed in situ helps the crops to fix the nitrogen from the atmosphere and enrich the soil wealth. These leguminous crops contain the Nitrogen fixing symbiotic bacteria in their root portion which can easily fix the atmospheric nitrogen. It is high time that we should think of the green manures to preserve the soil wealth and improve the agricultural production.

Soil Inoculants for Soil Wealth

Soil wealth preservation is a must sustain the agricultural production. The soil enrichment is made artificially by using chemical nutrient supplements. To maintain the soil wealth it is better that we use the Soil Inoculations. They are found to release the soil nutrients for the plant use to grow in a healthy manner.

These soil inoculates are nothing but the bacteria and few types of fungi incorporated into the soil to do this helpful job. By virtue of their symbiotic nature they are able to fix the atmospheric nitrogen as well. A type of bacteria called “rhizobacteria” which lives symbiotically in the root system of legume crops acts as the soil inoculate.

In the fungi side you can come across mycrorhizal which attach too many species of plants and facilitate the conduct of water and nutrients to the plants. The soil inoculates also help the plants to fight against certain pathogens causing diseases. They are helpful in warding of the diseases as they act as the antagonistic organisms against the plant pathogens.

Laser To Attack Space Junk

In the space, each and every nation is trying to take part in exploitation by sending various satellite and space shuttles. The debris created by such objects is increasing day by day in the space and the size vary from 0.5mm to the size of a bus. It is estimated that around 200,000 such objects are floating in the space as the remains of the rockets, space shuttle and other equipment sent to the space.

The presence of such particle pose a great danger to the newly sent rockets and the shuttles. An Australian company has come out with a solution for this issue. They have developed a laser tracking system to stop the debris from colliding with the space crafts and the satellites. The lasers fired from the earth can locate and track the debris protecting the objects sent to the space.

The technology has been developed with an investment of $3.5mn by the company named Electric Optic Systems in Australia. Let us hope that this will help to protect the human being from being hit by such flying articles at the speed of about 30000 kph., in the space.

Importance of River Linking

River linking is a major aspect that is discussed in every nation where the water source has become critical. Water derived during rainy season is drained into the sea in a major quantum without any use from the down flowing rivers. If such rivers are linked with each other the wastage of water can be prevented and also out into the best use both for irrigation and industrial use. Added to that the ill effects of such flood is also thwarted. Though the investment is on the higher side in the initial stage the benefit that is to be reaped is enormous at a latter date.

Gain Body weight

Body weight can be gained through many ways when everyone is worried about reducing the weight. One should also maintain the body weight to resist certain ailments. The food that one takes decides the body weight. The calorie one uses in his daily routine is also the deciding factor to take appropriate food items which ultimately helps him to gain weight. For normal activeness one should have reasonable and appropriate weight with relevance to the height and the energy spent in attending to various works.
