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. -

Kumar et al. Agric & Food Secur (2018) 7:31 https://doi.org/10.1186/s40066-018-0183-3 Agriculture & Food Security REVIEW Open Access Millets: a solution to agrarian and nutritional challenges Ashwani Kumar1,2* , Vidisha Tomer2, Amarjeet Kaur1, Vikas Kumar2 and Kritika Gupta2 Abstract World is facing agrarian as well as nutritional challenges. Agricultural lands with irrigation facilities have been exploited to maximum, and hence we need to focus on dry lands to further increase grain production. Owing to low fertility, utilization of dry lands to produce sufcient quality grains is a big challenge. Millets as climate change compli- ant crops score highly over other grains like wheat and rice in terms of marginal growing conditions and high nutri- tional value. These nutri-cereals abode vitamins, minerals, essential fatty acids, phyto-chemicals and antioxidants that can help to eradicate the plethora of nutritional defciency diseases. Millets cultivation can keep dry lands productive and ensure future food and nutritional security.

ICH/UNHCR Handout 3 Section 1 Nutritional Requirements For people to be healthy and productive they need a certain amount of nutrients. This is called their nutritional requirement. • The amount of energy that people get from their food is measured in kilo calories (kcal). • The average person needs about 2100 kcal each day • 17-20 % of this energy should come from fat • At least 10 % of this energy should come from protein • People also need certain amounts of vitamins and minerals • For example the average person should have at least 12 mg of the B vitamin niacin, 28 mg of vitamin C, and 22 mg of iron each day. -
