- How would green manure and soil microorganisms work together in enhancing soil fertility and crop yield? Name the targeted element and TWO (2) additional benefits brought by green manures to the soil?There is a general statement that "organic matter content of Pakistani soil is low" ,why?Why is a small volume nebulizer preferred over an MDI.
- true or false 2.) When the crop is badly lodged, mechanical harvesters are virtually useless and harvesting has to be done manually 3.) For measuring moisture content during harvesting, the most practical option is to use a resistance-type moisture meter that gives quick results and only uses small samples. 4.) Grain in the field dries naturally as the crop matures, giving up moisture to the air until the grain moisture is in equilibrium with the moisture in the air 5.) Most pests that cause deterioration in stored grains require a maximum amount of moisture to grow and reproduce.Although the market value of compost is negligible, many communities have implemented yard waste composting systems. Explain why?Fertile soil is one of the keys to good yield. (i) Explain the roles of clay and organic matter in contributing to soil fertility and cation exchange capacity (CEC). (ii) Name ONE (1) negative effect of low CEC and high CEC soils respectively. Suggest ways to improve low CEC and high CEC soils. (iii) Suggest ONE (1) suitable type of crops for high CEC soil, low CEC soil and loam soil respectively.
- State the colony shape, margin, and elevation of the nutrient agar colony exposed in : A. Nutrient agar in Soil B. Nutrient agar in Water C. Nutrient agar in Plant leaves D. Nutrient agar in AirThe practice of crop rotation uses nitrogen fixation to create fertile fields. First, a plant without a nitrogen-fixing relationship, such as corn, is planted. After the harvest, a nitrogen-fixing plant replaces the initial crop. Instead of harvesting the nitrogen-fixing plant, however, it is plowed under. The cycle continues in this manner. Crop rotation would allow the farmer to reduce which of the following? a) Planting seeds. b) Watering the fields. c) The use of manufactured fertilizer. d) The burning of fossil fuels by farm equipment.Starvation proteins are produced by a crop during which of the following segments of the growth curve? A) Logarithmic (or exponential) phase B) Stationary phase C) Death Phase
