Question

Why is delta land good for farming?

Answer 1

delta land is good rich river bottom land that when it floods nutrients are deposited from other areas that make delta land rich, and usually though delta land is in an area where there is a lot of clay, delta land has a lot of sand in it because it has been deposited in the area and this makes for a rich sandy clay loam excellant for crops and drainage and its very fertile where you dont need to add a lot of fertilizer and it is usually very flat land easy to farm

Answer 2

Because it tends to flood (in the case of the Nile, on a yearly basis) and the flood waters deposit sediments that contain nutrients which improve the quality of the soil. Also, there is  water available nearby for irrigation, which is a major problem in arid land. Hope this is helpful!

Answer 3

All that Char mentions is sound... in most cases irrigation will never be needed, but systematic drainage may be.

However, there are often short periods of salt water flooding, and it takes a rain or flooding from the river to wash the salt out.

Delta land is often best suited to growing crops that are very tolerant of wet conditions, such as rice.

It has been observed that the Nile delta lands have lost much of their agricultural virtue since the High Aswan Dam has cut off its annual flooding, and is filling up with the soil that used to be carried down to the delta.

Very large delta lands in Bangladesh have been subject to such severe flooding that only hardy and fools want to go on farming it. Crop losses have been catastrophic. But they really have to go on farming it.

Answer 4

Delta land is deep rich top soil deposited as sediment from former floods. It is flat ground and excellent for farming.

Answer 5

Delta land is good for farming, as rivers deposite silt on the land arround the river couse when it flood.

Silt is basily soil that has been washed away from other parts of the country and they are high in the key plant nutritional values.

Also in the area the soil called Loams develope.

Take the land arround Wisbech, in Cambridgeshire. The soil looks almost black as it is so full of the good stuff that feed plants. The area at one point used to be marshland on the coast of the wash, with the river Neine flowing through it. The Romans were the first people to start to reclaim it from the sea, and now Wisbech is about 12 miles inland rather than being on the coast.

Anway here is a more indepth reply as sombody did not approve of my last answer that I have left here as well:

This is what is stated in my book titled: Introduction to Crop Husbandry - including Grassland (5th edition) by J.A.R Lockhart & A.J.L Wiseman ISBN0-08-029793-5



Silts:- Characterstics. These soild which contail a high proportion of silt (up up to 80% or more). The particals (between clay, and sand in size) pack together very closley and r****d the movement of water.

Bad drainage is one of the main problems with these soils. They do not have a stable subsoil structure such as found in clay soils. The particals do not group togetherreadily and firmly and so úickly block up drainage cracks and tilew drains. Unlike clay, the siklt particles cannot take part in chemical reactions, so adding lime is not healful:it is very difficult to create an easy working soils structure. Frost has a very useful effect.

Management & Cropping:  Arable cropping isw verry difficult and these areas are best left down to permanent grass. Deep rooted plants, such as Lucern, left growing for several years, are likely to be helful in opening up the subsoil with their roots and so facilitating drainage.

There is notmuch land of this type in the British Isles: the best examples are found in the Lower Weald in Sussex.

Note: the fenland silts are Alluvial material, consisting of clay, silt and fine sand and vary in texture from sandy to medium loam. These soils are very fertile and faily easy to work. They are cropped intensively with all kinds of arable crops - the main ones are wheat, potatoes, sugar-beat, peas, seed production from root crops and grasses, bulbs & market gardening crops.

I hope that my answer helps.
