Agricultural soil science

Discussion The nitrate and phosphate levels shown in through my data relates to my hypothesis since it proves that the epigeic earthworms in the soil increased the nutrients in the soil, since the average nitrate and phosphate levels increased from tests 1-3. The results from this experiment showed that the control group increased their phosphate levels more so than the experimental groups, which contained the red wriggler earthworms. This could have been due to high amounts of Ca²⁺ in the water…

crops on agricultural lands have been identified as an essential management practice with the potential to positively impact water quality by reducing the loss of water soluble nutrients, such as a nitrogen nitrate or NO3--N, from the soil due to rain and irrigation, which is also known as nitrogen leaching. Water quality is also positively impacted from sediment transport, or the movement of inorganic and organic particles by gravity and water. These crops serve to capture excess agricultural…

Temperate deciduous forests themselves are affected greatly by global factors, like climate change, and human agriculture (Reich et al 2002); the woody plants that populate the majority of them are distributed based on things like soil moisture, soil nutrients, soil pH, flooding patterns, elevation, and light (Hosner 1958, Bell 1980, Menges 1983). These factors play into how the species interact and compete with one another, and how…

In today’s time, our world’s knowledge of agriculture has decreased in the last hundred years, but even more in agricultural activity. In 1860, seventy-five percent of the United States was involved somehow in agricultural production, now that percentage is less and two percent. As our nation continues to increase in population so does the need for agricultural products and land. With land being used more for settlement and buildings than for farming, being able to provide enough food for our…

guarantee Act 1988 (VIC). It is in the Bioregion of the Victorian Volcanic Plain, the catchment area is Corangamite, and the EVC is 55 Plain Grassy Woodlands. The reserve is 11-hectare triangle-shaped area, soil is sandy/stony loam, greyish brown in colour, ph. 6.5, water repellent is low with soil strength moderately firm, there is medium amount of…

check the health of your soil to know the perfect timing. Generally late summer and early autumn are the best time for the same. Lawn aeration is one of the best ways to take care of your lawn. With this process, you can let the water and air into the soil in order to relieve the compaction. Compaction is a general phenomenon which makes soil tighter and poses a problem for the air and water to reach the soil’s pores. With the help of this system, you can give keep your soil profile in good…

Two seeds were planted in the same garden. The arid soil gave the seeds small hope of flourishing into lively plants. One of the seeds was cared for by a gardener who loved and protected it; the seed grew to be a beautiful plant. Likewise, the other seed had a gardener who took care of it. This gardener loved the seed as well, however due to lack of responsibility and absence of the gardener, the prospective seed perished. This is the image that comes to me when I read The Other Wes Moore by Wes…

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…

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 to the agricultural land. Bush…
