What is the name of the process through which land becomes infertile from overuse?
Land that has become infertile from overuse has undergone a process called degradation. Some specific kinds of degradation include desertification, salination, acidification, alkalination, dereliction, and erosion. The process of making farmland fertile again after degradation is called remediation.
What causes CMP?
CMP is the result of the normal aging process, overuse, injury, or uneven pressures exerted on the knee joint.
What reason is there to explain the overuse of coal?
I'm not sure what you mean by overuse. When the industrial revolution started in the early 1800's and steam engines were invented, coal was the obvious fuel. Oil was hardly known and in fact whales were hunted to get oil for lamps. When oil was dicovered in the late 1800's it rapidly took a lot of the coal market as it was much easier to use and didn't involve so much hard manual labor. Coal has almost stopped being used except for electricity and steel making, so your question is puzzling.
Is the silica sand good for concrete mixed and can you help me about chemical ingredient that help increase concrete durability and strength?
I will pass on the silica sand item and the strength increases. Try the portland cement association site. As for durability, the most success I know of has been the use of air entraining agents in concrete. My experience is in roads and bridges. A 6% air entrainment (one was called Darex) dramatically improves the ability of concrete to withstand freeze-thaw cycles. Test specimens that I saw had been put through thousands of cycles. The non-air sample was pitted, spalled, pockmarked while the air mix looked pristine. The amont of air entraining agent is critical because it reduces the strength of the mixture (solid sand,and stone particles have been replaced by microscopic air voids). There are hundreds of ways to improve strength and early development of strength. The biggest effect is overuse of the chemical h2o. Also, in the long run air entrainment maintains strength longer because of the durability increase.
What causes high blood potassium?
The condition called hyperkalemia, or high blood potassium, is usually caused by other diseases and conditions. These include Type 1 diabetes, Addison's disease, acute kidney failure, chronic kidney disease, alcoholism and drug dependency, overuse of potassium supplements, and severe injuries or burns that cause red blood cell destruction.

What are some things that might limit resources or threaten survival for plants?
Things that might limit resources or threaten survival for plants would include items like overuse of fertilizer or pesticides which can damage the soil. Also, pollution and smog can threaten survival for plants because these interrupt the light that plants require.
What are the necessary characteristics of a good farmer?
Good farmers use good farming techniques, like rotating crops and planting buffer zones when growing GMO crops. They also know when to plant and when to harvest, though this can vary somewhat from season to season. They also implement good weed and insect controls so as not to overuse synthetic fertilizer and pesticides that pollute the environment.
What are 4 major causes of soil degradation?
Soil erosion and depletion are the major threats to soil as a resource. Both human and natural factors can lead to degradation of soils . Factors which lead to soil degradation are deforestation, overgrazing, overuse of chemical fertilisers or pesticides, rain wash, landslides and floods.
What are the problems of the worlds food supply?
Global warming may affect globai food production, the overuse of pesticides which is said to be killing all the bees will affect plant pollination.
What are examples of problems with the world's food supplies?

What can compost do to the number of leaves on a plant?
Increase or respect the anticipated number is the impact of compost upon the number of leaves on a plant. Dark-colored, fresh-smelling, nutrient-rich compost serves as a plant-friendly soil amendment, fertilizer or mulch. Its proper application tends to give plants the necessary number of leaves whereas its overuse promotes growth of roots and shoots at the expense of flowering and fruiting.
What causes soil exhaustion in Brazil?
There are a number of causes of soil exhaustion in Brazil. Some of the main causes include pesticides, artificial fertilizers, overuse of the soil without allow it to rest and so many more.
Why is the use of chemical to control pests discouraged?
The chemicals (poisons) used usually don't affect only the targetted species, but - perhaps to a lesser degree - also other species. Also, overuse of pesticides can lead to the target species developing resistance, especially in cases in which only one mode of action is used consistently to control or suppress the pest. The use of pesticides should always be considered the "last resort," after all other methods of integrated pest management have failed to control the pest to an economically acceptable level.
