Plot size

Particle-Size Equations It is common practice to plot size-distribution data in such a way that a straight line results, with all the advantages that follow from such a reduction. This can be done if the cui ve fits a standard law such as the normal probability law. According to the normal law, differences of equal amounts in excess or deficit from a mean value are equally likely. In order to maintain a symmetrical beU-shaped cui ve for the frequency distribution it is necessary to plot the population density (e.g., percentage per micron) against size. 

Plot size should be large enough to apply the test material, to obtain more than twice the required samples (most crops require a total of 12-kg sample weight) and to be able to use appropriate harvesting equipment. 

Spray volume should be based on the stage of growth of the plant. Spray volume is calculated based on plot size shape and stage of growth of the crop. 

This author recommends a minimum plot size of 4 rows x 200 ft for each treated plot. Foliar sampling would occur on the middle two rows with a 10-ft buffer on each end. Soil sampling would occur on each side of the middle two rows with a 10-ft buffer on each end. The 180-ft rows should be divided into 60-ft replicates designated as A, B, and C. The untreated plot should be 2 rows x 50 ft. For tree crops, 3 rows x 14 trees should be treated. The middle row should be sampled excluding the first and last trees.

Hazen (1914) developed a special grid for plotting size-frequency data so that the resulting curve is a straight line . This grid consists of a system of coordinates based on a probability scale, that is, a scale based on the probability integral. On this scale, which may be considered as the ordinate of the system, are plotted the cumulative percent oversize or... 

By this method the number of particles per traverse was calculated. The average number of particles in each size interval was progressively cumulated and the cumulated percentage of particles in each size interval was then calculated for making plots, size versus normalized cumulative percent on log probability graph paper. 

This relationship is found for each size interval. Similar expressions can be written for particle surface area or particle mass or volume. (It should be stressed again that particle volume converts directly to particle mass by multiplication of volume and particle density. Hence in plotting size distribution data, either one can be used to represent the other.)...

The modules are compact and are designed to be conveniently grouped together so that one module can be de-iced using electric heating while the others can remain on stream. Thanks to their small plot size they can be retrofitted easily (Fig. 2.11). The AGA... 

Two other statistical diameters are often encountered, viz. the modal and median diameters both are determined from frequency plots (size interval versus number of particles in each interval). The modal diameter is the diameter at the peak of the frequency curve, whereas the median diameter defines a midpoint in the distribution - half the total number of particles are smaller than the median, half are larger. If the distribution curve obeys the Gaussian or Normal Error law, the median and modal diameters coincide. 

Very early on, Aitken (1923) showed that most particles in the atmosphere are smaller than 0.1 pm diameter and that their concentrations vary from some hundreds per cm over the ocean to millions per cm in urban areas. Junge (1955,1963,1972) measured the atmospheric aerosol number size distribution and concentration in urban and non-urban areas as functions of altitude and site. He established the standard form for plotting size distribution data log of AN/ADp versus logD, where N = number and Dp = particle diameter. He observed that this plot was a straight line that could be described by the equation AN/ADp = AD, where A and k were constants. He also noted that in the range from 0.1 to 10.0 pm particle diameter, k was approximately equal to 4.0. This distribution mode was widely known as the Junge distribution or the power law distribution.

The implementation of this technology leads to a significant equipment and plot size reduction and, with it, to 20% less capital expenditure across the Liu-gi FBDB process chain. The development is accompanied by other improvements, for example, gas liquor treatment targeting zero liquid discharge [190,193-1953)3]. 

The Field Cultivation of Japanese Radish Seeds. The radish seeds coated with low molecular weight chitosan were cultivated in the field of the Tottori University farm in two autumn seasons (84 and 109 days, respectively) and one spring season (69 days) in 1984-1986. The results were compared with those of the uncoated seeds. Each experimental plot size was 0.75 x 3.5 m (2.6 m ).
