Soil fertility is critical for the provision of adequate food, fiber and renewable natural
resources(fuel,wood etc.). In the developing world soil fertility is linked to economic well
being of many farm families. Poor soils means poor harvest leading to low returns for the
over 60% of the population of developing countries relying on agriculture for survival.Use
of inorganic and organic fertilizers in addition to biological processes to improve the fertility
of the soil requires good understanding of their practical use and management.
Effects of compost, mycorrhiza, manure and fertilizer on some physical properties of a Chromoxerert soil field experiment was conducted to explore the role of mycorrhizal inoculation and organic fertilizers on the alteration of physical properties of a semi-arid Mediterranean soil (Entic Chromoxerert, Arik clay-loam soil). From 1995 to 1999, wheat (Triticum aestivum L.), pepper (Capsicum annuum L.), maize (Zea mays L.
To appreciate the complexities of the element mercury, it is enlightening to review the role of
Mercury — the god — in Greek, Roman, and Celtic mythology. Both the element and the
mythological god assume complex and ever-changing forms and functions.
In Greek mythology, for example, at the height of Aegean civilization around 1600 BCE,
Mercury (or Hermes as the Greeks called him) was known as the god of shepherds and animal
fertility (Aldington and Ames, 1968).
Because the ART industry is largely unregulated, we have very little data on who uses these
technologies. Until 2003, the only national data collected was through the Fertility Clinic
Success Rate and Certification Act of 1992, which requires that fertility clinics report the number
of pregnancies and live births from ART, which the Act defines narrowly as “fertility treatments
in which both eggs and sperm are handled in the laboratory” (e.g.
It is important to note that not all non-synthetic
materials (natural) are allowable, nor are
all synthetic materials excluded from use in
organic production. Notable exceptions include
insecticidal soap, a synthetic compound that
can be used in pest control, and tobacco dust,
a natural product that is not permitted. The
Organic Materials Review Institute (OMRI)
evaluates materials for use in organic agriculture
and publishes their findings in the form of lists of
allowable and prohibited inputs.
Organic production, however, does not
necessarily guarantee higher wholesale or retail
prices. A 2004 Organic Research Foundation
survey of organic farmers found that only 41%
of the respondents received a price premium
for all of their organic products. Another 86%
reported receiving a price premium on some
portion of their organically grown products.
Price competition with conventional products
and limited local demand (e.g. in rural areas)
are some of the reasons mentioned for failure
to receive price premiums.
Bokashi is an organic fertilizer, which is made by fermenting organic matter. The name Bokashi is a Japanese word, which means: fermented organic matter. Bokashi contains a lot of nutrients and it serves as a rapid working fertilizer.
The essential oil industry is under threat from numerous issues at present. Rising
agricultural input costs, particularly petrochemical based fertilizers and fuels are squeezing
farmers’ profit margins. Rising food prices and the increasing value of housing and industrial
land prices is creating competition for land, particularly around populated areas. Adverse
weather conditions and changing climate are creating both short and long term problems.
Poor crop yields are occurring much more regularly than before because of unusually heavy
rain, hail, floods, heat-waves and cold snaps....
It will be recollected that, in addition to its mineral portions, the soil contains organic matter in varied quantities. It may be fertile with but one and a half per cent. of organic matter, and some peaty soils contain more than fifty per cent. or more than one half of the whole. The precise amount necessary cannot be fixed at any particular sum; perhaps five parts in a hundred would be as good a quantity as could be recommended. The soil obtains its organic matter in two ways. First, by the decay of roots and dead plants, also of...
Specific micronutrient deficiencies may affect maternal and foetal health. Iodine deficiency
during pregnancy may cause foetal brain damage and mental retardation in infants. Vitamin
A deficiency increases the risk in pregnant women of infection and anaemia, may cause
blindness during pregnancy and early lactation, and has been associated to an elevated risk of
HIV mother-to-child transmission. Folate deficiency may cause severe foetal neural tube
defects like anencephaly and spina bifida.
The First Conference of French-Speaking African Countries on Men’s Participation in
Reproductive Health was held in Ouagadougou, Burkina Faso from March 30 to April 3,
1998. It was organized to share experiences and lessons learned over the past decade
among African organizations about communicating with men on reproductive health
Subsequently, the 1996 Nepal Family Health Survey, the 2001 Nepal Demographic and Health
Survey and the 2006 Nepal Demographic and Health surveys were conducted. This trend report
discusses key findings from these three DHS surveys in Nepal. All three Nepal DHS surveys sampled
nationally representative populations, were conducted by the same organization (New ERA Ltd.), and
managed by the same core group of survey personnel.
Storage of putative stem/progenitor cells is also an attractive research target in tissue
engineering. Collection of cells for tissue engineering is less invasive than conventional
tissue or organ transplantation. However, repetitive collection of cells can stress patients. If
the stem/progenitor cells could be stored, it is possible that they could be repeatedly used
for future therapy, reducing the burden and the cost to patients. The concept of banking
stem/progenitor cells in storage is not new. Stem/progenitor cell populations decrease in
size with age (D'Ippolito et al.
From April 2008 to April 2011, with the support of
grants from the Ford Foundation and the United
Nations Foundation (UNF) /United Nations Fund for
International Partnerships (UNFIP), WHO and UNFPA
developed and delivered a training programme
for their staff entitled “Strengthening capacity of
UNFPA and WHO to advocate for the integration of
sexual and reproductive health issues into national
development planning processes”.
Transkei, Ciskei, rural, peri-urban and urban consumers on the reasons for not consuming
organic products. The two main reasons advanced is that organic products are expensive
according to 60% of the consumers in the Transkei, 54.2% of consumers in the Ciskei,
62.5% of peri-urban consumers and 81.8% of urban consumers (see Table 1). The
second reason advanced is that organic products are not readily available according to
60% of the consumers in the Transkei, 70.8% of the consumers in the Ciskei, 80% of
rural consumers, 62.5% of peri-urban consumers and 63.
This project continues in the second half of 2006 to establish a new Macadamia Nursery and enhance three existing nurseries. In addition three major trials of different Macadamias are established, about 1 ha has 14 varieties suitable Macadamias, three provinces in northern Vietnam. In addition, the project is involved with three organizations implement 16 other tests. Training was done in the propaganda aspect, grafting, planting design and site preparation, maintenance and management of forest planting in the nursery and the test site.
The objective of waste water treatment is to prevent large quantities of substances to reach
and impact the environment in high doses and concentrations.
Areas of high population densitiy naturally are areas were production of sewage sludge is
high (see Figure 1-1). Presently about 8 million t of sewage sludges (MAGOAROU 2000) are
produced each year in the EU member states (Table 1-1). Its high content of organic
materials, of nitrogen and phosphorous suggest their use as soil conditioner and fertilizer
Graphic design is a creative process that combines art and technology to communicate ideas in print and electronic
media. Graphic design often refers to both the process (designing) by which the visual communication is created
and the products (designs) which are generated. Common uses of graphic design include identity (logos and
branding), websites, publications (magazines, newspapers, and books), advertisements, and product packaging.
Thorough evaluation of the infertile couple before in vitro fertilization (IVF) is critical in achieving the best outcomes and avoiding complications. Most IVF centers organize the evaluation by using a checklist that the nurse coordinator and physician assure is complete before proceeding with the cycle. DAY 3 FOLLICLE-STIMULATING HORMONE A level exceeding 25 mIU/ml (about 12 mIU/ml using current assays) has been correlated with a very low chance of pregnancy (1).
The history, culture and community values of East Africans are embedded in agriculture. It is the most
important source of livelihoods for millions of East Africans. The sustainable management of the
agriculture production process is therefore crucial if livelihoods are to be sustained.
Organic agriculture is a holistic production management system, which promotes and enhances agro-
ecosystem health, including bio-diversity, biological cycles and soil biological activity.
