Do not compost feces‚ dairy product‚ diseased plants‚ fish fat‚ and bones. Compost replaces mulch‚ plant food‚ and fungicide. Instead of wasting food scraps‚ turn it into compost. Landfill is one of the easiest places to get rid of trash. If the trash is not recyclable‚ donated‚ or compost material‚ then just throw it away. It is good to just get rid of the junk that

Ebio G-1L INTRODUCTION Farmers sure aim to have abundant and healthy agricultural produce but that became so elusive as the prevalence of disease-causing fungi or bacteria and defective planting materials remain a challenge. To cease all these through a necessary and effective pest management and disease control schema must be utilized. Using chemical pesticide would be a usual resort though

Ionic compounds are crucial to many chemical‚ biological and industrial processes. These compounds are capable of conducting electricity when dissolved in solvents such as water at the level of individual atoms‚ ions or molecules (Silberberg‚ 2010). Dissolving an ionic salt in water destroys its lattice structure and the individual cations and anions dissociate through the body of the water. This ionic dissociation results in the surrounding water molecules getting attracted to the released ions

According to author John Wargo‚ an additional five to six billion pounds of insecticides‚ herbicides‚ fungicides‚ rodenticides and other biocides are added to the world’s environment each year‚ with roughly one quarter of the amount released or sold in the United States (Lipson 3).

A community consists of populations of all the individual organisms in a specific area. A population consists of living things called organisms. Organisms break down into organs and organ systems which are more complex parts of organisms. Organs and Organ Systems are created by tissues which is

control agent for weeds. Among the three major types of pesticides (agricultural pest-control agents) herbicides are used to control weeds‚ or undesirable plants. (The other major classes of pesticides are insecticides‚ which control insects; and fungicides‚ which control fungi. Normally‚ any pesticide can only be expected to control‚ but not eradicate‚ agricultural pests.) In addition‚ the bioherbicide approach utilizes native plant pathogens that are isolated from weeds and are grown to produce large
