Black plastic and sawdust mulches were applied to ridged and flat rows it a 2-year (1956-1957) study of their effeci on romato culcure. Records were t;ken of soil temperatuie and moisrure 1e'els, ripe fruit to August 31' and total crop (ripe and green fruit).The highest early i'ield u'as obtained from the unmulched and sawdust plots bur"the hcai.iesr'total f.ield came from,.rhe blacl< plastic plots. Highest ioil temperature and iorveit moisture readings_ were recorded und,er the black plastic, and. lorvest so I temperature and highest moisture under the sawdust.The earliest ripe fruits came from the flat rows' but th.e-total. crop was significantly higher on the ridge rorvs. There was no significalt interactiol for mulches and row type.

“…Where aggregates are quite stable and exist as Part IV] Cr.AY TECIIXOLOGY IN SOIL SCIENCE 169 discrete units of characteristic shape and size, a determination of the proportion of the total soil combined into these aggregates can be used, to a large extent, as an index of the characteristics of the pore space. In such soil a fair degree of correlation has been found between the degree of aggregation and crop vields or productivity (Alderfer and Merkle 1944;Baver 1948;Olmstead 1947 ;Page and Willard 1947). In many soils, however, the aggregates may differ greatly in size, shape, or stability and quite, different volume-pore space relationships may result, depending upon how the aggregates themselves are arranged in the soil mass.…”

The physical properties of clay are of extreme importance in soil science. Plant growth, and hence crop production, within any environmental condition is largely controlled by soil structure which results from reactions involving clay. The active clay material in soil, particularly in combination with small amounts of organic matter, exerts a tremendous effect on soil properties. This effect may be on structure (the arrangement of soil particles), or on consistence (the response of the soil to mechanical manipulation). Where structure is favorable soil grains are clumped together into effectively larger aggregates so that soils have a more open arrangement and water and air can move freely and roots function normally. Where structure is unfavorable, soils tend to be heavy and impervious, and both the physical and chemical properties of the soil become unfavorable for plant growth. Soils which are low in clay, such as sands and silts, exhibit a rather narrow range over which physical properties can change and may be unfavorable for plants, being droughty and lacking in fertility. Structure of soil may change through action of natural forces, management practices, or cropping systems, and it is of great importance that we understand how structure affects plants, and how it is formed and stabilized by reactions involving clay. Combination of clay with relatively small amounts of certain organic compounds greatly changes the physical properties of the system and the nature of the combination and the mechanics of the soil structure-forming process are but little understood. Such changes greatly affect soil consistence and soil-water relationships as well as soil structure. The problem is made difficult since the results of any particular combination or change in clay characteristics must be interpreted not in terms of the clay system alone but in light of the resultant effect on the complex and dynamic system which constitutes a soil. Solution of such problems, however, may be of great importance to our future ability to produce food and fiber abundantly and efficiently from our limited soil resource.

“…Studies by Alderfer and Merkle (1943) and Findeling et al (2003) indicated that runoff was dramatically reduced by mulch in a moderately heavy rain (7.5 cm hr À1 ), and bare soil plots lost 40e60% of incoming rainfall to runoff, while pebble mulch gardens lost only 3e10%. Lightfoot and Eddy (1994) noted that lithic mulch could reduce soil erosion and increase water infiltration significantly, especially during periods of drought.…”
