Extractions: Regional Research Station, Bajaura Provision of irrigation, soil and water conservation and watershed development are necessary for sustainable agriculture. To save and conserve soil and water are to save life on earth. Therefore, to promote ecological and sustainable farming, provision of cheap water harvesting and storage tanks for irrigation, check dams, earthen cum stone field bounds and boundaries, conversion of outwardly slopping terraces or fields into inwards slopping fields, fuel-fodder grasses, tree plantations and afforestation for soil and water conservation on watershed basis have beeb taken up and continued on a large scale. Irrigation is the most important factor and input for the development of sustainable agriculture system, as it increases the efficiency of all other inputs too. Therefore, all sources of irrigation like rivers, streams, nullahas, springs, rainwater, etc. should be fully tapped, harvested and developed. Once irrigation becomes available, it is necessary to make changes in cropping patterns, cropping systems and cropping intensity by including more remunerative high value crops and the IIHFS. To increase the efficiency of irrigation, more efficient methods like sprinkler and drip irrigation must be used.

Extractions: Aquaguide: The problem of Leaky Ponds Missouri is a "pond state" with over 300,000 privately owned ponds and lakes. These ponds provide a source of water for humans, livestock, crops and fish. For these reasons most pond owners should be concerned about the amount of water maintained in their pond. Throughout the course of a year, a pond's water level (even those without a leak) will drop because of evaporation, seepage, and withdrawals for household use, livestock watering and irrigation. Evaporation is surface water lost to the atmosphere. In a dry year rainfall may not replace the amount of water evaporating from the pond's surface. Seepage is water lost through the soil. Well constructed ponds with good soil may lose one inch of water per month to seepage. The most recognizable signs of a leaking pond are rapid water level decreases or the water falling below the level expected with normal use. Wet spots and aquatic vegetation (like cattails) below the dam may be good indicators of seepage through the dam or around the drain pipe and may help determine the location of the leak. Why Do Ponds Leak?

Extractions: SALINITY - FERTILITY INTERACTIONS ON EARLY GROWTH OF MAIZE (Zea mays L.) AND NUTRIENT UPTAKE Pablo Zalba and Norman Peinemann INTRODUCTION MATERIAL AND METHODS RESULTS AND DISCUSSION CONCLUSIONS ... ABSTRACT INTRODUCTION Owing to the fact that ionic absorption always increases together with the salt concentration in irrigation water and soil solution, nutritional requirements of cultivated plants should be satisfied with greater difficulty. A large body of literature has been written on the effects of salinity on the nutrition with N, P and K by glycophytes from which the following information was selected: Nitrogen: There is ample evidence of root absorption competition between Cl- and NO3- by plants [ De Wit et al. (1963) for rice; Weigel et al. (1973) for beans; Berstein et al. (1974) for some vegetable crops; Kafkafi et al. (1982) for tomato]. However, there is no evidence to show that increasing amounts of nitrogen under saline conditions avoid such effect of competition. Phosphorus Potassium MATERIAL AND METHODS Effects of nitrogen, phosphorus and potassium applications under salinity were studied in separate experiments.
Extractions: B. Itier, INRA The purpose of this paper is to review irrigation scheduling methods using information given in the different papers presented to this FAO workshop. It will not only be a simple report of these papers, but it will contain part of the personal experience and opinion of the authors. It will not present methods and techniques in detail but will focus on the main subject of Theme 1, 'Applicability and limitations'. The objectives of irrigation management are well stated in Huygen et al. (1995): 'Maximize net return... minimize irrigation costs, maximize yield, optimally distribute a limited water supply, minimize groundwater pollution...'. To reach these goals, it is necessary to schedule irrigation accordingly, in other words, to decide 'which fields to irrigate, when and how much' (Hess, 1996), keeping in mind that overirrigation can have negative effects on quantitative and qualitative yield (Deumier et al.

FAQ Menu URL: http://res.agr.ca/lond/pmrc/faq/menu.html In a recent publication from the Research Branch of Agriculture and Agri-Food Canada entitled " The health of our soils: toward sustainable agriculture in Canada " (D.F. Acton and L. J. Gregorich, editors; 1995), the editors state that the terms Soil Quality and Soil Health can be used interchangeably. In a Statement on Soil Quality by the Soil Science Society of America [SSSA] (Agronomy News, June 1995, Page 7), the editors added the following Footnote on Soil Quality: The terms soil quality (favored by scientists) and soil health (favored by farmers) tend to be used interchangeably, especially in the general press. Characterization of soil quality by scientists focuses on analytical/quantitative properties of soil with a sep arately defined quantitative link to the functions of soil quality. Characterization of soil health by farmers focuses on descriptive/qualitative properties of soil with a direct value judgement (unhealthy to healthy)integrated into the options for a given property; in addition, interwoven into the properties of soil per se are value-based descriptive p roperties of plant, water, air, and animal/human systems considered by farmers to be an integral part of soil health characterization.
