Chapter 1 INTRODUCTION Situational Analysis Soil productivity is an important concern for farmers. Green manuring, crop rotation and mix farming are oftenly used to improve the soil fertility at the same time the nutrients used in plant growth are conserved and returned to the soil to enhance its fertility (Alberta Agriculture and Forestry, 1993). Green manuring is the plowing under or soil incorporation of any green manure crops while they are green or soon after they flower. Green manures are grown for their leafy materials needed for soil conservation (Boller et al., 2004). Plants are commonly used for green manuring have Rhizobia bacteria for nitrogen fixation similarly crop rotation is alternating legumes and non-legumes plants Most plants
Technology in Agriculture TO EDIT AND FIX FOR APRIL Technology has played an integral role in the process of developing the agricultural industry. Today it is possible to grow crops in a desert type environment by use of agricultural biotechnology. With this technology, plants have been engineered to survive in drought conditions. Through genetic engineering scientists have managed to introduce traits into existing genes with a goal of making crops resistant to droughts and pests. An example, A bacterium known as ”Bacillus Thuringiensis” acts like a reservoir , it enables crops to be insect-resistant , so these genetically modified crops will grow without any interference from pests, these are one of the many advances due to technology.
Foliar Fertilization -Introduction & Background. Roots are leaves in the ground, and leaves are roots in the air. —Alan Chadwick. For many years, cultivators have used foliar sprays to feed their crops. It help plants to gain all the nutritions that plants need through their leaves.
They make for both horizontal and vertical integration and thereby stimulate all round development of the rural economy. Role of Agro based Industries in Rural Development. - Rural agro based industries influence the rural economy in particular and the national economy in general. Agro-based industries by raising the income levels of the rural workers can bring significant changes in the standard of living and the social and cultural attitudes of the rural population in general. Further, rural agro based industries can contribute to the per capita income at the national level.
With the great finds in plant breeding brings the progress of mankind in terms of overall advancement in population, technology, and arts. We must know as much as we can about agricultural science because our world is needing more and more food
Soil with good tilth enhances aeration, water infiltration and uptake of minerals by plants besides minimizing erosion and crusting. Mycorrhizal fungi also have a positive influence on crop production. Basidiomycetes, ascomycetes or zygomycetes form symbiotic associations with some plants. The filamentous nature of mycorrhiza enables them to explore expansive soil areas to obtain limiting nutrients and water. This increases the water and mineral absorption capacity of their plant partners.
In fertilizer application, the main purposes and advantages of composting are waste stabilization, pathogen inactivation, nutrient and land reclamation, and sludge drying. Through theses processes, it can help maintain nutrient in the soil rather than destroying
1997, ArshadandMartin 2002). Soil has two qualities:inherent soil quality where a soil’s natural ability to function and dynamic soil quality where soil changes depending on how it is managed (USDA, 2006). Davidson (2000) noted that soil quality is an important conceptthat will make a distinctive and crucial contribution to soil management.That is why many scientists have been assessing soil quality for many purposes. Soil-quality assessmentis an effective method for evaluating the environmental sustainability of land use and management activities (Nortcliff, 2002).As reported by the Soil Quality Institute (USDA, 2006), the ultimate purpose of assessing soil quality is to protect and improve long-term agricultural productivity, water quality, and habitats of all organisms. But due to disturbances to soil such as building infastractures, cultivating and mining the soil, nutrients are lessened.
It intends to produce high quality, nutritious food that adds to preventive healthcare and wellbeing. Fertilisers, pesticides, animal drugs and food additives, which cause adverse effects are the inverse of health. 2 THE PRINCIPLE OF ECOLOGY “Organic agriculture should be based on living ecological systems and cycles, work with them, emulate them and help sustain
Daily waste can be divided into three ways; the main two are used for fertilizer from feces and urine that can help the soil and reusable food that feed our animals. Biochar promotes growth of beneficial soil microbes and reduces the need of chemical fertilizers. As an example, In India, coffee husk can be used as pig feed, bedding, and soil that is highly diversified case of products that helps with marked fluctuations and steady income. South America is known to have bio diversity in both plants and animals because of that they have sustainable farming systems that are good for commercial purposes this is convenient due to more crops and the reduced factor of endangered species. In addition, Fossil fuel farming is neither sustainable nor capable of providing resources for the increasing population due to different crops needed to be selected that is suitable for the environment.
