“…There are conflicting reports regarding the potential benefits derived from incorporating soil amendments into the backfill of transplanted trees and shrubs. Schulte and Whitcomb (1975) reported seeing no benefit from using amendments in the backfill soil of silver maple, Acer saccharinum L., and Corley (1984) found no consistent, positive growth responses when several difficult-to-establish landscape trees and shrubs were transplanted in traditional backfill amendments. In studies with 1-year-old red maple (Acer rubrum L.) and Washington hawthorne [Crataegus phaenopyrum (L.f.) Medic.]…”

Greenhouse studies were undertaken to determine the influence of composted media on the posttransplant growth of containerized red maple, sugar maple, and green ash seedlings. Before planting, the chemical and physical properties of each substrate were measured. For media containing composted biosolids, pH was significantly higher, whereas electrical conductivity, air-filled porosity, and total pore space were significantly lower than in a composted medium without biosolids. For composted substrates containing at least some soil, bulk density, particle density, and container capacity were all significantly greater than for composts without any soil. Growth of red maple was about the same in a noncomposted soilless medium (Metro-mix 360) as it was in substrates containing biosolid compost. Height growth, total biomass, and root biomass of green ash were all significantly greater for seedlings grown in Metro-mix 360 only, and the growth of sugar maple seedlings was about the same in Metro-mix 360 or in a composted substrate without biosolids (Metro-mix 560). The results of this study suggest no particular short-term growth advantage of using composted media as backfill amendments when transplanting; however, the addition of composts could be beneficial in improving the chemical and physical properties of native soils, particularly urban soils containing very low levels of organic matter.

“…Irrigation did not interact with soil amendment treatment, meaning that amendments did not affect survivability or growth of live oaks when irrigation was either minimal or plentiful after transplanting. This finding contradicts promotional literature distributed by manufacturers of many amendments but supports nearly all published studies on trees (Pellet 1971;Schulte and Whitcomb 1975;Ingram et al 1981;Corley 1984;Smalley and Wood 1995;Ferrini and Nicese 2002).…”

“…However, the fact that the roots did not develop into the surrounding soil, as was the case with all other treatments, may mean the trees would be more susceptible to drought. These data combined with that from other studies (Pellet 1971;Corley 1984;Kelting et al 1998;Ferrini and Nicese 2002) do not support use of soil amendments or liquid additives in backfill soil in the establishment and growth of newly planted trees, at least in good soil. Smalley and Wood (1995) also found increased root density within the backfill soil after amending it when planting balled-and-burlapped red maple (A. rubrum) into clay soil.…”

During the first and second year after transplanting into good soil, there was no apparent benefit from adding amendments to the backfill soil around newly planted 5 cm (2 in.) caliper live oaks (Quercus virginiana Mill.), nor was there a benefit from applying liquid additives over the root ball. Top growth in the first 2 years after planting was not enhanced on trees with amendments added to the backfill soil compared to the control. In the first growing season following planting, trees irrigated frequently (3 times per week for 38 weeks) grew about twice as fast as those irrigated only during the first 3 months after planting. There was no lingering effect of irrigation on top growth rates once irrigation ceased. Trunk diameter and height growth on trees treated with paclobutrazol (Profile 2SC) was less than on trees in all other treatments due to the growth-regulating effect of paclobutrazol. Root growth in the backfill soil was not affected by soil amendments added to the backfill soil at planting and was not affected by irrigation after planting in 5 of the 7 treatments.

“…A normal value of bulk density for clay soils is ranged between 1.0 to 1.6 Mg.m -3 and the normal values for sand is ranged between 1.2 to 1.8 Mg.m -3 , plants have a potential restriction at ≥1. 4 Mg.m -3 for clay and ≥1.6 Mg.m -3 for sand (Corley 1984). Generally, the bulk density affects the hydraulic conductivity to the extent that the soils with higher bulk density were having correspondingly lower hydraulic conductivity (Igwe 2005).…”

Many problems facing sandy, calcareous and heavy clay soils and restricts plant growth, nutrients availability and sustainable agriculture. Soil amendments are considered to be the most realistic soil management methods to improve soil chemical and physical properties. Improving some soil physical and chemical properties, study the correlation between soil properties and their effect on plant growth and nutrients uptake by faba bean plant (Vicia faba L. var.716) were the main purpose of this study. To achieve this purpose three factorial pot experiments were conducted by addition rates (0, 5 and10 ton. fed -1 ) of farmyard manure (FYM), phosphate rock (PhR) and rice straw (RS) either alone or mixed to sandy, calcareous sandy loam and clay soils. Soils were incubated with the studied treatments for 15 days before planting. The main results showed that the addition rates of soil amendments led to slightly increase in soil salinity, total porosity and significant increase in organic matter content in the experimental soils. Bulk density and pH decreased with increased the rates of FYM and PhR either alone or mixed with RS. Decreasing in hydraulic conductivity in sandy and sandy loam soils, while it increases in clay soil. Generally, there are negative correlations between soil organic matter and both of hydraulic conductivity and bulk density in sandy and sandy loam soils, while, organic matter and hydraulic conductivity gave a positive effect in clay soil. Changes in soil properties had a positive effect of faba bean growth and macro nutrients uptake. The highest rates of the studied materials showed a significant increase in fresh and dry weight, NPK content and uptake of faba bean plant. Integrated use of the highest rates of FYM and PhR with RS were the best option for sustaining physical and chemical properties, enhancing faba bean growth and nutrients uptake of the studied soils.
