|What is meant by Pesticide Residue?||Top|
|Pesticide Residues are the remains of Pesticides, applied by the formers for plant protection, existing inside or on the surface of the items in absorb form.|
|What major health hazards are caused by the Pesticide Residues?||Top|
|Health hazards associated with Pesticide Residues range from short term effects like skin irritation, eyes infection, Nausea, fever, headache to long term effects like lungs and kidney problem and cancer.|
|What is reason behind Pesticide Residue in food?||Top|
|Pesticide Residues are mainly caused by the none recommended use of Agricultural Pesticides on food commodities. Specially due to over dozing & improper application timing.|
|What are the remedies to help avoid Pesticide Residues in food?||Top|
|Pesticide should be applied strictly according to the departmental recommendations and/or the label instructions.|
|What is the implication of Pesticide Residues regarding foreign trade?||Top|
|According to the present scenario, commodities carrying Pesticide Residues above the Maximum Residue Limit (MRL) are strictly prohibited in modern international markets.|
|What are the top five food commodities in Punjab which are highly effected with Pesticide Residues?||Top|
|These top five commodities are Tomato, Chili, Bitter Guard, Sweet Paper and Tori.|
|What are the top five food Pesticides whose residues are occurring in food commodities across in Punjab?||Top|
|These top five Pesticides are Imidacloprid, Lufenuron, Carbandazim, Acetamiprid and Chlorpyrifos.|
|What is effect of cooking process on Pesticide Residues?||Top|
|Cooking process finds its food effectiveness in reducing Pesticide Residues in food commodities.|
|What are meant by MRL values, PHI &PGI?||Top|
|Is there any facility in province of Punjab for farmers/ exporters to get their produce checked for pesticide residues?||Top|
|There is a Pesticide Residue Laboratory in Kala Shah Kaku working on the subject under Government of the Punjab, Agriculture Department.|
|What is soil pH?||Top|
|It is defined as –ve logarithm of hydrogen ion activity in a solution. It is the measure of acidity and alkalinity in soils.|
|Why pH of soil is important in plant nutrition?||Top|
|Availability of nutrients generally depends on soil pH and the nutrients which are required by most of the plants are available in a pH range of 6.5-7.5.|
|What are essential nutrients?||Top|
|A chemical element essentially required for the normal growth and reproduction of plants.|
|How many nutrients are essential for plants?||Top|
|There are twenty one 21 nutrients which are necessary for the growth of plants i.e. Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, Sulfur, Boron, Chlorine, Copper, Iron, Manganese, Molybdenum, Zinc, Cobalt, Silicon, Sodium, Vanadium and Nickel.|
|What is soil fertility?||Top|
|The ability of soil to provide nutrients to the plants for growth is called soil fertility.|
|What are macronutrients?||Top|
|The nutrients required by plants in large quantity are called macronutrients i.e. Nitrogen, Phosphorus and Potassium.|
|What are the secondary nutrients?||Top|
|Calcium, Magnesium and sulfur are termed as secondary nutrients because they are rarely limiting and more rarely added to soil as fertilizers.|
|What are micronutrients?||Top|
|The nutrients required by plants in small quantity are called micronutrients i.e. Boron, Chlorine, Copper, Iron, Manganese, Molybdenum, Zinc, Cobalt, Silicon, Sodium, Vanadium and Nickel.|
|Why organic matter is important for soil fertility?||Top|
|It stabilizes soil structure, improves aeration, porosity, infiltration and ultimately improves soil health.|
|Why organic matter status of our soils is very low?||Top|
|Organic Matter of our soil is low due to high temperature and low rainfall.|
|What are the major sources of organic matter?||Top|
|Farm Yard Manure, Humic acid, City Waste, Compost, Poultry Litter, Biochar and Press Mud.|
|What is the different between organic and inorganic fertilizers?||Top|
|Organic fertilizers are derived from living organisms such as animal and plants e.g. manures.
Inorganic fertilizers are man-made chemicals, formulated to improve soil fertility.
|What is compost?||Top|
|It is a mixture of organic residues and soil that have been piled up and allowed to undergo biological decomposition.|
|What is humus?||Top|
|A brown or black organic substance consisting of partially or wholly decayed vegetable or animal matter that provides nutrients for plants and increases the ability of soil to retain water.|
|What is humic acid?||Top|
|Humic acid is a principle component of humic substances which are the major organic constituents of soil (humus), peat and coal.|
|What is urea?||Top|
|It is a form of nitrogen fertilizers with Nitrogen 46%.|
|What is DAP?||Top|
|Di-ammonium phosphate is one of a series of water soluble ammonium phosphate salts that can be produced when ammonia reacts with phosphoric acid.|
|What are the sources of potassium fertilizers?||Top|
|Sources of potassium are as under:
|What is the difference between soil application and foliar application of fertilizer?||Top|
|Application of any fertilizing substance in a liquid form by spray is called foliar application and incorporation of fertilizers in soil is called soil application.|
|What are the soil related problems in Pakistan?||Top|
|Soil related problems are:
|Why soil pH of our soil are high?||Top|
|In arid and semi arid environment where soil are rich in bases (calcium, magnesium, sodium and potassium) and contain soluble carbonates and bi-carbonates which produces OH- , soil pH is high ranging from 7-10.|
|Why P deficiency is most prominent in our soils?||Top|
|In our soil Phosphorus react with soil calcium and form unsoluble compound.|
|What is the role of soil texture for crop production?||Top|
|Soil texture is responsible for the movement of air and water through the soil due to its pore space and size.|
|What is C:N?||Top|
|It is ratio of mass of carbon to mass of nitrogen in a substance. It serves as an indicator for nitrogen limitation of plants.|
|Why micro-organisms are more important for soil fertility?||#|
|Micro-organisms play a major role in the decomposition process and the formation of humus. The promote plant growth, produce plant hormones, fix nitrogen and facilitate mineralization.|
|What is environmental pollution?||Top|
|Environmental pollution is the contamination of the earth’s biological and physical components which include water, air and land. This leads to their depletion to an extent that normal environmental processes are seriously affected.|
|What is nitrate leaching?||Top|
|Downward movement of excess nitrate ions in soil freely with drainage water is called Nitrate Leaching.|
|What are heavy metals?||Top|
|The metals with high atomic #, weight and specific gravity more than 5 g/cm3 are called heavy metals. They include some metalloids, transition metals, basic metals, lanthanidse and actinides.|
|Why nitrates are hazardous for human health?||Top|
|High levels of nitrates in water can adversely affect oxygen level for both humans and aquatic system. Human health issue include blue baby syndrome.|
|What is the green manuring?||Top|
|It is practice of growing lush plants on the site into which you want to incorporate the organic matter than turning into the soil while it is still green.|
|What is bio-fertilizer?||Top|
|It is a substance which contains living micro-organisms, which when applied to soil increase the supply of primary nutrients to plants.|
|What is integrated use of chemical fertilizer?||Top|
|It is the application of organic and inorganic fertilizers in combination for plant growth.|
