Soil contamination

about a man scattering seeds on four different types of ground: along a path, rocks, thorns, and healthy soil. Where the seeds fell on the path, birds have come by and eaten them, when the sun came up the seeds that were thrown on the rocks had shriveled up and died, the seeds on the thorns grew little but were then choked out by the thorns, but the seeds that had been planted on the healthy soil grew abundantly (The Bible, NIV). The seed that is thrown along the path exemplifies a believer…

NATURAL LONGEVITY OF TREE SEEDS. The period for which seed can remain viable without germinating is greatly affected by its quality at the time of collection, its treatment between collection and storage and the conditions in which it is stored. According to Harrington (1972) one of the two main factors influencing seed longevity is seed moisture content. Seeds are hygroscopic and their moisture contents come into equilibrium with those of the atmosphere. Nevertheless, seed longevity varies…

A Discussion on the effect of Bush Encroachment on the Agricultural land in Namibia. Definition: bush encroachment is the thickening of indigenous woody plant species and their incursion into area they did not occur abundantly before (Axel Routhauge, 2014). It can be unplanned conversion of vegetation dominated by grassland to one dominated by woody species, often as result of overgrazing or invasion by aliens. This essay aims to clarify more on the various effects that bush encroachment cause…

Lebanon might not be denoted as major agricultural country due to its size; however its geographic location around Mediterranean coast and climate regarding high mountains and fertile valley aimed in cultivating all kind of crops and fruits. Porter’s methodology & hypothesis can be related to Lebanese agricultural sector confirming and illustrating how each components interact through analysis of factors and derives considerable advantages from basic Factor Conditions. Lebanon relies on physical…

2.2. Importance of nutrients in sheep production Importance’s of Nutrients are substances, that supplied by animals used as feedstuffs, for body maintenance and production. Adequate amount of energy’s, proteins, vitamins and mineral supplements are essential nutrients to improve the productivity of sheep fatting. According to Cannas et al. (2004), Adequate supply of energy and protein in the sheep balanced diet are important to enhance meat production and to protect the sheep from weight loss,…

When flowers or plants are sensitive to climate and may not be suitable to the climate in which it is sold, the retailer definitely maintains the responsibility to alert customers of the growing conditions prior to purchase. Like all products, adequate disclosure remains necessary on the flowers. A reasonable consumer would assume, that if not told otherwise and based on past experiences with the Palles’ flower shop, that the flowers were locally grown and would fit their geographic climate. The…

Pigeonpea (Cajanus cajan (L.) Millsp.), also known as Redgram, is an economically and nutritionally important grain legume crop belonging to the Cajaninae sub-tribe of the tribe Phaseoleae under sub-family Papilionoideae of family Leguminosae. Considering the vast natural genetic diversity in the germplasm and the presence of many wild relatives, India is considered as the primary center of origin of pigeonpea (Van der Maesen, 1980). It is one of the hardy, drought tolerant and important pulse…

Natural pastures are the main sources of feed for ruminants, and form the major feed component of domesticated livestock in Ghana. However, unfavorable rainfall pattern, uneven seasonal growth and unavailability of pasture during certain times of the year have been considered the major limitations to constant supply of forage for ruminants. There are two seasons in Ghana, the dry and wet season. Forages are normally abundant in the wet season but this is in reverse to the dry season. These…

Plants gain a lot of nutrients in their daily lives. They get it mostly from water and also the soil. Water is a molecule made up of the following atoms, Hydrogen and Oxygen. In this molecule the electrons are not shared equally between these atoms. Electrons are negatively charged so if they spend more time around an atom the atom becomes negative. The electrons turn Oxygen negative because they spend more time together. The reason for the electrons to be around Oxygen is because Oxygen has…

(Morgan, Bending and White, 2005) The interaction between plants and beneficial microbes is necessary for the protection of plants, both from pathogenic microbes (Whipps, 2014) but also the buildup of toxic substances which the plant may absorb from the soil. (Morgan, Bending and White,…
