After going through the following story, I have decided to propagate the idea of SOLAR AID team......

The extended rainy season finally appears to be relenting. This is great news for us since many rural roads have been impassable lately. The clinics and schools we evaluate and install with solar power are in the shadow of development and extremely hard to reach at the best of times.…

I have gone thorugh the work of Water 1st International. Thay are doing good work. hence I thought of spreading message of CARRY 5 Walk for Water – Seattle, Washington – June 5 so that the EVOKERs who are nearby may join for a nobel cause.

SAVE THE DATE!

Seward Park, Seattle

Individual and team participants will fill their containers with water from Lake Washington and try to carry 5 gallons of water for 5 kilometers along Lake…

Agroforestry is an integrated and sustainable system of land use combining agriculture, forestry, horticulture, livestock management and agrostology. With the shrinking per capita land availability, agroforestry system with the integration of perennial woody trees with crops/pastures…

This include, loss of nutrients and organic matter, acidification associated with removal of nutrients or misuse of fertilizers, increased leaching by soil exposure due to removal of vegetative cover, increased temperatures and oxidation of the soil organic matter due to exposure and cultivation, salinization…

Here are some sources of light which are used in absence of electricity:

Hi, EVOKErs,

Good day!

Here is a link for viewing a different approach to the MDGs.

For a different approach to the MDGs: watch the film "8". This series of eight short films was made by famous producers such as Gus Van Sant, Wim…

In 2020, I would like to develop a converter for generating electricity and become an entrepreneur. How? read on.....

All electromagnetic waves essentially possess both magnetic and electrical properties. Hence, any such waves can be converted to electricity. Also it can be stored for future…

I got the following success story in energy. Hope EVOKErs will find it useful. Thanks.....

Delta-Montrose Electric Association Home Energy Makeover Contest: Many of us braved this winter by slipping on gloves to keep our fingers warm as we dutifully wrote a check to the utility company. As energy rates continue to climb, is there really anything we can do but pay bigger utility bills?

What about…

This blog is the result of demand from some of my EVOKEr friend who wanted my opinion on urban food growing solution in view of phosphorus scarcity (both in terms of availability in soil as well as market). Here I go…..…

After searching net, I think the following from Georgetown University, USA has it.

Drinking and cooking kill in developing countries. Diarrheal illness caused by dirty water and respiratory disease caused by smoke inhalation from wood fires are the two leading environmental causes of disability and death in the world, representing 10% of the total global burden of…

I was going through lot of current ideas of electricity generation. Suddenly, I could come across this one submitted by Beckerjon. Hope all will find it useful.

"Using our knowledge of antenna and microwave circuits as well as antenna optimization technologies, we will investigate technologies that can convert a wide spectrum of light (IR, solar, UV) into…

Phosphorus is one of the immobile nutrients in the soil. It occurs in the soil in both organic and inorganic forms, the latter being of greater importance in mineral soils. Inorganic P is known to occur in three main categories, viz., apatite which is a…

Acid soils can be naturally occurring, however, a number of agricultural practices have expanded the areas of such soils. Main causal factors include crop offtake of basic ions and use of fertilizers those leave acidic residues. Leaching of nitrate also results soil acidity. Nitrate is infinitely soluble in water and leaches below the root zone at a…

Non-judicious use of irrigation water irrespective of its quality leads to soil salinization and sodification. Continuous acc**ulation of salts in root zone results into soil salinization. These salts may come from irrigation water, mineral dissolution, precipitation, capillary rise or all of these. The process of sodification…

The process of increase in the ratio of hydrogen and aluminum ions in comparison to basic cations within the soil resulting in the adverse effects on root growth and metabolism of plant is called soil acidification. The problem is more prevalent in the uplands. Poor organic matter content of the soil results in low pH buffering…

The question that was troubling me for quite sometimes now is a post by Alchemy ‘Episode 3 STORY: Did the EVOKE Network fail?’ The mere utterance of…
