Helping The Farmer Case Study

Improved Essays
Question: A farmer comes to see you and ask for your help. His corn has low yield.
1. What kind of information you would need to know in order to help the farmer? (5 points)
Water
When corns were got deficient water. Thus, corns were not substrate for photosynthesis rate and stress. Corns produced less carbohydrates and starch that affect to yield. Root phenotype is long and short .long root is deep in soil for absorption of underground water. Short root is spread wide root at absorption of top soil for water and nutrients. When corns were got a lot of water or flood. Sometimes root of corns were not oxygen. Corn is low photosynthesis rate.
Light
Corns are low photosynthesis rate at low intensity light because photosynthetic pigments are
…show more content…
Root hair length is long and root is long at deep soil.
And closed stomata whereas air is dry its connect to carbon dioxide and refer to accumulate food (photosynthesis).

3. How would you provide short and long-term solutions to help the farmer using the knowledge you had learnt in the class? (10 points).
Short-term
The first step Soil measures at soil analysis when we were got analysis results. Soil is acid. Farmer will apply CaCO3 compound. CaCO3 compound will help to adapt soil from acid soil to natural soil. Plants cannot use phosphorus because availability of phosphorus (P) in soils is phosphate ion. It has soluble water of phosphate.
Low of Phosphorus in soil. Farmer will add phosphorus fertilizer or Mar fertilizer, Dolomite fertilizer, Rock phosphate.
High of Phosphorus in soil, It may be phosphorus for function. Farmer must add water or microorganism living.
Agricultural practice
Crop rotation. He must be rotated plant for plant absorb nutrient. Other plant absorbs different volume and type of nutrient. long-term adaptation of soil structure for root. Root is good function. conventional breeding techniques is improved plant for phosphorus

    31.8kg/ac = 78.55kg/ha 120 – 78.55 = 41.45 Therefore, 78.55kg of nitrogen will come from manure, leaving the option to spread up to 41.45kg of nitrogen on the field to aid the crop in growing, and staying within the regulation of SMR1. Further to this, there are a number of Good Agricultural and Environmental Conditions (GAECs) that must be considered when growing an over-winter forage crop. GAEC 5 states that “You must have minimum land management which reflects site specific conditions in order to limit erosion.” [DEFRA (2015) The Guide to Cross Compliance in England]. This includes limiting poaching in order to limit soil erosion, and not complying with the GAEC can result in the loss of some or all of a BPS or Stewardship Scheme payment if the total area of livestock damage is a continuous distance of greater than 20 metres long and 2 metres wide near a vulnerable watercourse. Summary In summary, this assignment has shown that it is important to consider the laws surrounding, and therefore the use therein, of fertiliser when growing forage crops.…

    The only problem that doesn’t hold a solution is the clearing of ecosystems and loss of biodiversity. Most of the solutions involve soil conservation using policies and other farming techniques. Crop rotation helps to restore nutrients in the soil and minimize erosion. Contour farming helps to slow runoff and capture soil, also some plant buffer strips of vegetation on the borders to lessen erosion and water pollution(Brennan, Withgott pg. 239).…

    CAPACITIES IN THE PLANT These amino acids are additionally used in creating vital proteins and structural parts of the plant and can get to be a piece of the put away proteins in the grain. Nitrogen serves as the hotspot for the dim green shading in the leaves of different products. Nitrogen consolidated with high centralizations of chlorophyll uses the daylight as a vitality source to carryout fundamental plant capacities including supplement uptake. Phosphorous:- How is hydroponics much better than soil? In nature, rich soils contain three important factors that a plant needs to grow.…

    The problems of low NUE in organic agriculture are more complex than the simple adjustment of fertilization methods. In the absence of synthetic N application, N uptake depends on the size of the root absorbing area and root uptake efficiency, existing inorganic N and potential N mineralization reserves in the soil (Spiertz & De Vos, 1983). Since the principle is based on utilization of already existing ecological systems and recycling process, the main concept in the improvement of NUE in organic agriculture is to maintain existing residual N as well as to recycle on-farm materials such as green manure, and incorporate plant residue from previous crops which are available for a long mean residual time (Spiertz & De Vos, 1983; Drinkwater, 2004;…

    2.1 Soil The soil is a major source and natural medium for plant growth which has a direct impact on yield and quality of crops growing on it. 2.1.1 Nutrients in soil Most plants raise by absorbing nutrients from the soil. Soil is a major source of nutrients needed by plants for growth and development. There are two main classification of nutrients in the soil; Macronutrients and Micronutrients. Carbon (C), Hydrogen (H), and Oxygen (O) are also essential for plant growth, but not considered as soil nutrient because these taken from the air and in water.…

    In addition to compost decreasing the amount of waste going to landfills, using compost persuades gardeners from using chemical fertilizers. Chemical fertilizers and pesticides are responsible for water contamination. For excessive enrichment of ponds, rivers and lakes is due to an overuse of chemical fertilizers. Due to composting preventing the use of chemical fertilizers this will put help put an end to water contamination. Therefore, yes, compost can have safety and health concerns, but compost is helping benefit our environment, while putting prevention to environmental…

    Legumes can be a natural solution to adding nitrogen to the soil in agriculture. One study done in Australian found that the nitrogen added to the soil by soybean when rotated with sugarcane “lowered [nitrogen] fertilizer requirement…necessary to maintain sugarcane yield” (Parker, 2010). This study shows how agriculture can benefit when more natural approaches are taken and how much of an impact legumes may have on nitrogen levels in the…

    On the other hand, Brazil’s land shows degradation, but Brazil reduces the impact of conventional cultivation by using strip cropping or intercropping. Non-till farmers intercrop cover crops with food crops such as wheat and soybeans. The climate in Brazil varies from tropical to temperate and therefore over half of all cropland is under no-till cultivation because the heavy rainfall promotes erosion, causing tilled soils to lose organic matter and nutrients and the hot weather can overheat tilled soil, so no-till is very helpful. The results of the use of the…

    It’s an approach which utilizes natural cycles, organic supplements, and sustainable methods that reduce erosion. The goal of organic farming is to replace the use of synthetic fertilizers, herbicides and insecticides with ecological management skills, and more natural ways of introducing nutrients to soil. Characteristics of organic farms include maintaining high levels of organic matter and biological activity, nutrients supplied through slowly available nutrients for microorganisms to utilize, the use of legumes to fix nitrogen, and controlling weeds, diseases, and pests through crop rotation, natural predators and biodiversity (Araujo & Melo, 2010, p. 2420). Several management skills are present in organic farming which reduce erosion such as contour farming, terracing, and shelter-belts; thus allowing crop production on areas such as hillsides, mountainous regions and windy planes. Other methods help soil fertility and crop protection such as crop rotation, intercropping or planting diverse plants together, and no-till farming (Withgott & Laposata, 2015, p. 143-144).…
