Book excerpt: Excerpt from Soil Moisture: A Record of the Amount of Water Contained in Soils During the Month of July, 1895 It will be seen that the soils differ very markedly in their texture. The truck soils of the Atlantic Coast contain from 1 to 10 per Cent of clay. As a rule, the less clay they contain the earlier the crops mature, which is the most important element in truck farming. A soil con taining between 4 and 5 per cent of clay, as shown in this sample, is an average truck soil adapted to any Of'the usual truck crops. The truck soils, as a rule, consist of from 70 to 85 per cent of the different grades of sand. The finest tvpe of grass land In the Eastern States, on the other hand, contains a very much larger percentage of clay. It contains not more than 5 or 10 per cent of the various grades of sand and from 28 to 50 perc cent of clay. On account of this marked difference in the texture of these soils, they maintain, even with the same rainfall, very different conditions of moisture, and this adapts them to different classes of crops. The trucking interest depends upon the early maturity of vegetables and small fruits, so that they can be put upon the market before there is competition from other soils of the State. It is carried oii under a very intense system of cultivation. The value Of the truck crops of Maryland is about equal to the value of the wheat crop and nearly equal in value to the corn crop, but the truck farming is confined to a narrow belt of land along the coast and Chesapeake Bay, and in the aggregate there is not more than one-tenth of the corn acreage devoted to this interest. This is without considering the market gardening around the larger cities and the production of fruits, which would very materially increase the relative importance of this class of agricultural crops without greatly extending the acreage. These truck soils do not yield as much per acre nor is the quality Of the crops produced as fine as on the heavier soils of the State, but vegetables can be forced to mature early and be placed upon the market during the winter and early spring months sometime before they can be matured upon the heavier soils.

Book excerpt: Excerpt from Soil Moisture: A Record of the Amount of Water Contained in Soils During the Month of May, 1895 Sir: I have the honor to transmit herewith a report upon the amount of water contained in some important types of soil in different portions of the United States. The marked effect of different amounts of rain upon the yield and quantity Of crops is familiar to all in the everyday experience of farmers. It will be seen from these records that, owing to the difference in the texture of soils, even with the same amount of rainfall, soils retain very different amounts of water. As crops require very different conditions of water for their best development, this dif ference in the water content of soils very largely accounts for the peculiar adaptation of certain soils -to certain classes of crops. A good truck soil in a favorable season will contain about 5 per cent, or one twentieth of its weight, of water; and grass land, on the other hand, should contain 20 per cent, or one-fifth of its weight, of water; These are characteristic differences due to the peculiar texture of these lands and their relation to water. The actual amount of water contained in the soil determines the character of the season, the actual amount of rainfall being no reliable measure of this. These records show the actual conditions of moisture available to plants in these soils. It is not possible at present to draw reliable deductions from these records until more data is collected, and they are therefore given for the present with little comment.

This book was released on 2005-04-14 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural droughts affect whole societies, leading to higher food costs, threatened economies, and even famine. In order to mitigate such effects, researchers must first be able to monitor them, and then predict them; however no book currently focuses on accurate monitoring or prediction of these devastating kinds of droughts. To fill this void, the editors of Monitoring and Predicting Agricultural Drought have assembled a team of expert contributors from all continents to make a global study, describing biometeorological models and monitoring methods for agricultural droughts. These models and methods note the relationships between precipitation, soil moisture, and crop yields, using data gathered from conventional and remote sensing techniques. The coverage of the book includes probabilistic models and techniques used in America, Europe and the former USSR, Africa, Asia, and Australia, and it concludes with coverage of climate change and resultant shifts in agricultural productivity, drought early warning systems, and famine mitigation. This will be an essential collection for those who must advise governments or international organizations on the current scope, likelihood, and impact of agricultural droughts.

Book excerpt: Excerpt from Soil Moisture: A Record of the Amount of Water Contained in Soils During the Month of June, 1895 The records showing the conditions in the West are all commented upon directly under the diagrams. AS a rule, during th1s favorable season the fields under ordinary cultivation and those which had been subsoiled and subsequently cultivated do not Show very different mois ture conditions. In some places the-effect of cultivation is not appar ent upon the moisture content of Soils. For reasons which have already been, given it is not to be expected that cultivation would Show a very marked effect upon the amount of. Moisture in the soil either in a very dry season or in a very favorable sea-son with frequent rains. The time when it would have its maximum effect would be after a wet season and when a dry period was coming on. The moisture content at this time should fall much more gradually in the cultivated than in the uncultivated land. This is shown to a slight extent in some of the records, but not to such an extent as would seem likely to occur under the most intelligent Cultivation of the soil. The small amount of data which has been collected is not sufficient, however, to warrant a close and final judgment in this matter.
