Managing Potassium for Organic Crop Production by Robert Mikkelsen an Adequate K Supply Is Essential for Both Organic and Conventional Crop Production
NORTH AMERICA Managing Potassium for Organic Crop Production By Robert Mikkelsen An adequate K supply is essential for both organic and conventional crop production. Potas- sium is involved in many plant physiological reactions, including osmoregulation, protein synthesis, enzyme activation, and photosynthate translocation. The K balance on many farms is negative, where more K is removed in harvested crops than is returned again to the soil. An overview of commonly used K fertilizers for organic production is provided. otassium is an essential nutrient for plant growth, but it often receives less attention than N and P in many crop Pproduction systems. Many regions of the U.S.A. and all of the Canadian provinces remove more K during harvest than is returned to the soil in fertilizer and manure (Figure 1). In the U.S.A., an average of only 3 units of K is replaced as fertilizer and manure for every 4 units of K removed in crops, resulting in a depletion of nutrients from the soil and increasing occur- rences of deficiency in many places. Potassium is the soil cation required in the largest amount by plants, regardless of nutrient management philosophy. 1,400 Removal 1,200 Hay and forage crops can remove hundreds of pounds of K from the soil Manure each year, placing a heavy demand on soil resources. 1,000 Fertilizer Large amounts of K are required to maintain plant health 800 and vigor. Some specific roles of K in the plant include os- moregulation, internal cation/anion balance, enzyme activa- 600 tion, proper water relations, photosynthate translocation, and 400 protein synthesis. -
Comparison of Three Approaches for Cultivating Lettuce, Mint and Mushroom Herb
agronomy Article Nutrient Management in Aquaponics: Comparison of Three Approaches for Cultivating Lettuce, Mint and Mushroom Herb Valentina Nozzi 1, Andreas Graber 2 ID , Zala Schmautz 2 ID , Alex Mathis 2 and Ranka Junge 2,* ID 1 Department of Life and Environmental Science, Università Politecnica delle Marche, via Brecce Bianche, 60131 Ancona, Italy; [email protected] 2 Institute for Natural Resource Sciences, Zurich University of Applied Sciences, Grüental, 8820 Wädenswil, Switzerland; [email protected] (A.G.); [email protected] (Z.S.); [email protected] (A.M.) * Correspondence: [email protected]; Tel.: +41-589-345-922 Received: 10 February 2018; Accepted: 5 March 2018; Published: 7 March 2018 Abstract: Nutrients that are contained in aquaculture effluent may not supply sufficient levels of nutrients for proper plant development and growth in hydroponics; therefore, they need to be supplemented. To determine the required level of supplementation, three identical aquaponic systems (A, B, and C) and one hydroponic system (D) were stocked with lettuce, mint, and mushroom herbs. The aquaponic systems were stocked with Nile tilapia. System A only received nutrients derived from fish feed; system B received nutrients from fish feed as well as weekly supplements of micronutrients and Fe; system C received the same nutrients as B, with weekly supplements of the macronutrients, P and K; in system D, a hydroponic inorganic solution containing N, Ca, and the same nutrients as system C was added weekly. Lettuce achieved the highest yields in system C, mint in system B, and mushroom herb in systems A and B. The present study demonstrated that the nutritional requirements of the mint and mushroom herb make them suitable for aquaponic farming because they require low levels of supplement addition, and hence little management effort, resulting in minimal cost increases. -
Changes in Agriculture of the Green Revolution States: Implications for Agricultural Development
Aerie. Econ. Res. Rev., Vol. 5(1), 1992 CHANGES IN AGRICULTURE OF THE GREEN REVOLUTION STATES: IMPLICATIONS FOR AGRICULTURAL DEVELOPMENT SURESH PAL*, MRUTHYUNJAYA* AND PRATAP S. BIRTHAL** ABSTRACT This paper examines the changes in the agriculture of green revolution states. The results revealed that a decrease in the share of agriculture in state domestic product was not accompanied by appropriate fall in the workers in agriculture. Consequently, man-land ratio increased over time, markedly in West U.P. The share of purchased and energy based inputs has increased over the years and formed about 50 per cent of the operational cost. The share of capital in gross value added was substantially higher than that of human labour in the production of wheat, whereas the share of capital and human labour was almost equal in the case of paddy. A sharp decline in the returns to management in the production of wheat calls for developing cost saving technology and reappraisal of price policy. The adoption of new seed-fertilizer based technology and large capital investment (both private and public) in key inputs, particularly in irrigation, have ushered in the "Green Revolution"(GR) in India in the mid-sixties. Consequently, crop production has registered an impressive growth. Because of strong input-output linkages in modern technology, the growth in agriculture was also accompanied by the overall economic development (Bhalla et a!, 1990). However, certain issues relating to structure of agriculture have become important in the period of green revolution which need attention. The new technology is suspected on the ground that while transforming the subsistence agriculture into commer- cial farming, it may induce the well-off farmers to accumulate more and more land through tenancy eviction, purchasing land from marginal and small farmers and encroaching on commons. -

Increase Food Production Without Expanding Agricultural Land
COURSE 2 Increase Food Production without Expanding Agricultural Land In addition to the demand-reduction measures addressed in Course 1, the world must boost the output of food on existing agricultural land. To approach the goal of net-zero expansion of agricultural land, improvements in crop and livestock productivity must exceed historical rates of yield gains. Chapter 10 assesses the land-use challenge, based on recent trend lines. Chapters 11–16 discuss possible ways to increase food production per hectare while adapting to climate change.

This chapter evaluates projections by other researchers of changes in land use and explains why we consider the most optimistic projections to be too optimistic. We discuss estimates of “yield gaps,” which attempt to measure the potential of farmers to increase yields given current crop varieties. Finally, we examine conflicting data about recent land-cover change and agricultural expansion to determine what they imply for the future. -
The Philippines Impact of the Green Revolution on Agriculture Rice: the Primary Crop Major Events of the Green Revolution
The Philippines Impact of the Green Revolution on Agriculture Rice: The Primary Crop Major Events of the Green Revolution • 1960s- the government of the Republic of the Philippines with the Ford Foundation and the Rockefeller Foundation established IRRI (International Rice Research Institute) • 1962- the IRRI crossed Dee-Geo-woo-gen and Peta rice strains • 1968- IR8, or “miracle rice,” was formed • 1981- the use of miracle rice reaches 81% of total rice crops Benefits • IR8, “miracle rice,” produced ten times the amount of rice as traditional varieties • As a result of the switch to farming IR8, annual rice production in the Philippines increased from 3.7 to 7.7 million tons in 2 decades • The large increase in rice production allowed the Philippines to become an exporter of rice for the first time in the 20th century Environmental and Agricultural Problems • Chemical fertilizers used in conjunction with miracle rice eroded soil • Increased rice production led to increased water consumption • Pesticides and fertilizers used in rice farming polluted water and caused siltation • Declining water quality poses a threat to future rice production, due to the high amount of clean water required to grow rice • The Philippines did not have sufficient funding to improve irrigation systems→ fell behind neighboring countries • Vulnerable to recurring natural disasters, which posed a large threat to the agriculture-based economy Rice Production Afterwards • 1973- the Philippines experienced domestic/international problems causing a downfall in economic
