“…The potting medium used is much higher in organic matter and has a greater air pore volume (40%) than the soils in the nursery beds. Davis et al (2006) found adding relatively high additions of organic matter to nursery soils produced larger seedlings with larger root volumes although the response was strongly dependent on the type and quantity of the materials used.

“…Although planting stock quality is difficult to quantify (Haase, 2008), the most reliable morphological indicator of quality and future survival and growth in the field continues to be basal stem diameter because it is highly correlated with many metrics of root system size (Davis & Jacobs, 2005;Dey & Parker, 1997;Tsakaldimi et al, 2013;Wilson & Jacobs, 2006). Recent studies have shown that field performance of bareroot nursery stock can be improved by increasing the amount of organic matter in nursery beds (Davis et al, 2006) or decreasing seedling bed densities to produce larger seedlings (Schultz & Thompson, 1996). Field performance has also been improved by undercutting or selecting seedlings for high numbers of lateral roots (Ruehle & Kormanik, 1986;Schultz & Thompson, 1990, 1996.…”

Benefits of repeated air-root-pruning of seedlings when stepping up to progressively larger containers include excellent lateral root distribution immediately below the root collar and an exceptionally fibrous root ball. To evaluate long-term field performance of repeatedly air-root-pruned container stock, three plantings of swamp white oak (Quercus bicolor Willd.) 10 to 13 years old were located that also included bareroot planting stock. Initial and final stem diameter and height and above-ground green weights were determined on randomly selected trees at each site. On a site with a sandy, excessively drained, high pH soil, trees (age 10) from container stock were 1.5 times taller, 2.3 times larger in dbh, and 2.8 times greater in green weight than trees from bareroot stock which averaged only 2.9 m tall, 3.9 cm dbh, and 16.3 kg green weight. On a site with high clay, poor internal drainage, and frequent flooding, trees (age 12) from container stock were 1.4 times taller, 1.8 times larger in dbh, and 4.1 times greater in green weight than trees from bareroot stock which averaged 4 m tall, 7.3 cm dbh, and 28 kg green weight. On an upland site with deep loess soils, there was a trend for trees (age 13) from container stock to be only slightly larger than trees from bareroot stock with each stock type averaging 9.6 m tall, 20 cm dbh, and 177 kg green weight. Repeated air-root pruning produced lateral roots immediately below the root collar * Corresponding author.J. W. Van Sambeek et al. 164 that resulted in large container stock with large well-balanced root systems that were competitive on harsh or less than ideal oak sites. Although the process is relatively labor intensive, propagation of repeatedly air-root-pruned container stock is readily adaptable internationally to locally available sources of organic matter and open-bottom containers.

“…Chicken manure was chosen as the organic additive, which had undergone natural decomposition outdoors for nearly 12 months prior to the experiment and consisted of a local mixture of chicken feces and some soil from the southeastern part of the nursery. Chemical analysis revealed that total N, P and K contents within the chicken manure were 11.93, 8.22 and 12.34 (Davis et al 2006, Irshad et al 2013. More specific properties of the chicken manure used in the present study can be found in Wei et al (2012a).…”

Sustainable agriculture often requires the incorporation of organic matter into cultural protocols as an amendment to mitigate problems caused by chemical inputs, but the responses of transplanted seedlings to such additions have not been well quantified. In this study, bare-root Changbai larch (Larix olgensis Henry) seedlings were applied with 100 or 200 kg nitrogen (N) ha -1 of inorganic fertilizer with or without chicken manure added at a rate of 10,000 kg ha -1 during nursery cultivation, obtaining four treatment combinations designated as F100+, F200+, F100-, and F200-, respectively. Over-winter seedlings were transplanted into pots and placed in a growth chamber, where the carbohydrate metabolism, biomass accumulation, root respiration, and new root number were quantified. Both initial soluble sugar and total non-structural carbohydrate (TNC) accumulation were the lowest in the F100+ treatment. However, two months later, root soluble sugar content was the highest in this treatment, while coarse-root (diameter > 2mm) carbohydrate content was the highest in the low rate of inorganic fertilizer treatment. During the two-month post-transplant period, the net carbohydrate accumulation rate (NCAR) for starch was negative for all treatments, but the NCAR value for soluble sugars was the highest in the F100+ treatment at both the root and whole-plant scales. Relative to the F200-treatment, the NCAR value for soluble sugars, final sugar content, and biomass accumulation in coarse roots, respiration rate of fine roots (diameter ≤ 2 mm), and new root number were all greater in the F100+ treatment, while new root number was increased by organic matter additions. In conclusion, the use of chicken manure as an organic amendment had the potential to enhance transplanted larch seedling performance by improving post-transplant new root number, but this application must be considered within the context of the interaction between organic amendment treatments and inorganic fertilizer applications.

“…The beneficial effect of compost utilization on plant growth has been reported in many greenhouse-and nursery-crop production systems (e.g. Holopainen et al, 2002;Wilson et al, 2002;Davis et al, 2006). However, the studies also show that the plant response to compost addition depends on the plant species (Wilson et al, 2002), the inherent properties of the compost and the functionality of the composting method (Raviv, 2005).…”

“…The research and use of other alternative growing-medium materials and soil amendments have greatly increased during recent decades (Bunt, 1988;Carlile, 2005;Davis et al, 2006), because of the need to cut costs associated with the use of growing media and also partly because of the increasing concern about overextraction of peat. The beneficial effect of compost utilization on plant growth has been reported in many greenhouse-and nursery-crop production systems (e.g.…”

The suitability of using composted forest-nursery waste as a component in growing medium was studied. Norway spruce [Picea abies (L.) Karst.] seedlings were grown in containers filled with sphagnum peat (100P), forest-nursery waste compost (100C) and in peat mixtures containing 25 or 50% compost by volume (75P25C and 50P50C, respectively). Morphological and chemical characteristics of the seedlings and the water and nutrient contents of the growing media were studied during 22 weeks of nursery cultivation. The seedlings were outplanted the following spring, and the survival and growth were followed for 3 years. Compost additions decreased seedling height, diameter and shoot dry mass, but root dry mass was the same in 100P and 75P25C after nursery cultivation. Foliar nutrient concentrations were optimal in all the seedlings, although foliar nitrogen content was lower the greater the proportion of compost in the medium. Compost additions did not affect the root-egress potential tested before outplanting. The 100P seedlings grew significantly more than the other seedlings during the first summer at the forest site. Thereafter, compost additions did not affect growth, but the final height and diameter were still the lowest in 100C. The results suggest that forest-nursery waste compost has potential to be used as a component of peat-based growing medium. However, specially adjusted nursery-cultivation practices need to be used for compost-containing media.
