foundation it is ’shallow’. Shallow foundations (sometimes called ’spread footings’) include pads (’isolated footings’)‚ strip footings and rafts. Shallows foundations are used when surface soils are sufficiently strong and stiff to support the imposed loads; they are generally unsuitable in weak or highly compressible soils‚ such as poorly-compacted fill‚ peat‚ recent lacustrine and alluvial deposits‚ etc. Pad foundations Pad foundations are used to support an individual point load such as that due to

Crop rotation should replace mono-cropping. As the name implies this is a system of farming whereby different crops are planted on the same piece of land in succession. This benefits the land since different plants use different nutrients from the soil. Pastures should be subdivided to allow for rotation of grazing. Ploughing

Laccaria laccata was multiplied using Modified Melin Norkrans (MMN) medium and inoculated into rooted plantlets in vermiculite having MMN/ MS medium or in soil under in-vitro conditions. Plantlets died within 1 and 2 months of inoculation in vermiculite and soil respectively. This may be attributed to the ready availability of nitrogen and phosphorus in MMN and MS media and more competency

Land degradation has become one of the primary issues of concern arising from the human interaction with the lithosphere. It encompasses soil degradation and the deterioration of natural landscapes and vegetation.

receive as much sunlight as possible throughout the day. After you have located a spot to grow your garden‚ you should examine the soil. You will want to see if the ground is rich in top soil. Sometimes the ground can seem like its rich in top soil but it can be sand or clay. The spot that you choose also needs good drainage. Vegetables will not grow on poorly drained soil‚ even if you use the best fertilizer money can buy. The next step to have a successful garden is making the rows. This way your
