Soil erodes naturally, but human activities can greatly speed the rate of soil erosion, leading to diverse ecological effects an
igor_vitrenko [27]

Answer:

Methods of soil conservation are listed below.

Explanation:

The major sources of soil erosion include water,wind and tillage. In order to mitigate or prevent soil erosion, some of the following techniques can be implemented:

  1. <u>Contour Farming: </u>Planting in row patterns that run level around a hill — as opposed to the up and down the slope pattern.This reduces runoffs and consequently water erosion.
  2. <u>Crop Rotation:</u> This involves planting crops with high residue (e.g corn, small grains, e.t.c) in rotation,as the layer of residue would protect the topsoil.  
  3. <u>Built in structural diversion</u> : Used often for gully control, to regulate flow of water away from the field and through designated desired paths.
  4. <u>Conservation Tillage</u>: This involves methods such as no-till planting, strip rotary tillage, etc, which do not allow the soil surface to be smooth and bare, but instead  covered with crop residue that protects the soil from eroding forces.

A mixture of 18 % 18% disinfectant solution is to be made from 16 % 16% and 23 % 23% disinfectant solutions. How much of each so
jeka94

Answer: 20 gallons of 16% and 8 gallons of 23% solution is usedfor 28 gallons of the 18 % solution.

Explanation:

According to the dilution law,

C_1V_1+C_2V_2=C_3V_3

where,

C_1 = concentration of ist disinfectant solution = 16 %

V_1 = volume of pure acid solution = x gallons

C_2 = concentration of another disinfectant solution= 23%

V_2 = volume of another acid solution= (28-x) gallons

C_3 = concentration of resulting disinfectant solution = 18 %

V_1 = volume of resulting acid solution = 28 gallons

16\times x+23\times (28-x)=18\times 28

x=20galllons

(28-x) = (28-20) = 8 gallons

Thus 20 gallons of 16% and 8 gallons of 23% solution is usedfor 28 gallons of the 18 % solution.
