Cut slopes are frequently generated by construction work in hilly areas, and artificial soil is often sprayed onto them to promote ecological rehabilitation. The artificial soil properties are very important for effective management of the slopes.

Determination of Chemical and Physical Soil Properties

Soil properties along a toposequence is a key to sustainable crop and soil productivity, hence the need to study the effect of toposequence and soil depth on physical and chemical properties of soil around Federal College of Forestry, Ibadan, Oyo-State. Soil samples were collected from three soil depth 0 - 30 cm, 30 - 45 cm, and 45 - 60cm from four profile pits that was dug along the toposequence, crest, sedentary, middle and valley bottom for analysis of physical, morphological and chemical properties following standard procedures at the laboratory. The highest total porosity values was recorded at the valley bottom of the forest The highest saturated hydraulic conductivity was recorded at the crest of the forest Likewise bulk density values at the crest of the forest 1. The highest 52 mg kg -1 and the lowest 1 mg kg -1 available P values were recorded at the valley bottom layers of the forest land soils and sedentary of the forest land soils, respectively. The highest exchangeable Ca was found in the valley bottom of forest soils 4.

Physical and Chemical Properties of Soil

Soil texture: Soil texture defines the proportion in which the soil separates to make the mineral component of the soil.

Chemical and physical properties Ion exchange Depending on deficiency in the positive or negative charge balance locally or overall of mineral structures, clay minerals are able to adsorb certain cations and anions and retain them around the outside of the structural unit in an exchangeable state, generally without affecting the basic silicate structure. Through a series of demonstrations and hands-on exercises, students are taught how to determine soil texture by feel and are given the opportunity to examine other soil physical properties such as soil Sub-samples of soil from each location were further ground to pass through mesh sieve for determination of organic matter.

Physical properties of soil

The amount of water, air and nutrients available for plant growth is affected by the soil physical properties and turf management practices that include watering, mowing, and aerifying and how much the fields are used. Determining the physical properties of your soils will ultimately help you determine how to manage them effectively. Coarse-textured soils sands, loamy sands, sandy loams have a large particle size and do not have great water and nutrient holding capacity. They tend to be well drained, dry out faster, and are less likely to compact. Fine-textured soils clays, sandy clays, silty clays have a small particle size. They can hold water and nutrients, take time to dry out, can be easily compacted when wet and often are associated with poor drainage that limits the use of the fields during wet weather. Knowing the soil type is important and can differ from area to area and from field to field.

Mineral fraction of soil consists of particles of various sizes. According to their size, soil particles are grouped into the following types Table The particle sizes of above groups are suggested by International Society of Soil Science. In India, international system of particle differentiation is commonly followed.

Она старательно расшифровывала текст, завороженная тем, как на первый взгляд произвольный набор цифр превращался в красивые стихи. В тот момент она поняла, что нашла свою любовь - шифры и криптография отныне станут делом ее жизни. Почти через двадцать лет, получив степень магистра математики в Университете Джонса Хопкинса и окончив аспирантуру по теории чисел со стипендией Массачусетского технологического института, она представила докторскую диссертацию- Криптографические методы, протоколы и алгоритмы ручного шифрования. По-видимому, ее работу прочел не только научный руководитель, потому что вскоре последовал телефонный звонок, а затем по почте ей доставили авиационный билет от АНБ. Все, кто имел отношение к криптографии, знали, что о АНБ собраны лучшие криптографические умы нашей планеты. Каждую весну, когда частные фирмы начинают охоту за талантливой молодежью, соблазняя ее неприлично высокими окладами и фондовыми опционами в придачу, АНБ внимательно наблюдает за этим, выделяет наиболее подходящих и удваивает предлагаемую сумму.

Готова спорить на любые деньги, что он. Чутье мне подсказывает.  - Второе, что никогда не ставилось под сомнение, - это чутье Мидж.  - Идем, - сказала она, вставая.  - Выясним, права ли. Бринкерхофф проследовал за Мидж в ее кабинет.

Директор метнул на нее настороженный взгляд, но Мидж уже бежала к аппарату. Она решила включить громкую связь.

Движимый страхом, он поволок Сьюзан к лестнице. Через несколько минут включат свет, все двери распахнутся, и в шифровалку ворвется полицейская команда особого назначения. - Мне больно! - задыхаясь, крикнула Сьюзан.

 - Да-да, я и ищу спутницу.  - Беккер понял, что совершил какой-то промах. - Да, наше агентство предоставляет сопровождающих бизнесменам для обедов и ужинов.

 Отключить. Черт побери, немедленно отключить. Мидж появилась в дверях со свежей распечаткой в руке.

 Боже мой, конечно. Беккер ощутил тупую боль в желудке. - У кого же .

Все будет прекрасно. Приближаясь к пиджаку защитного цвета, он не обращал внимания на сердитый шепот людей, которых обгонял. Прихожане могли понять нетерпение этого человека, стремившегося получить благословение, но ведь существуют строгие правила протокола: подходить к причастию нужно, выстроившись в две линии. Халохот продолжал двигаться .

 Сьюзан, - наконец произнес он еле слышно.  - У меня нет семьи.  - Он посмотрел на .
