In order to determine
different bio solid nutrient (macro and micronutrients) inputs and sugar beet
productivity, field trials were conducted to investigate the effect of N
application as sub-optimal level (66% of the recommended rate) when combined
with three bio-solids (plant compost farmyard manure (FYM) and chicken manure)
at four levels (3, 6, 9 and 12 t fed^-1) in newly reclaimed sandy
soil. The results showed that the total N content on a dry solids basis, indicated that chicken
manure contained 31% more N compared with the average content in FYM and 79%
compared to the plant compost. Plant compost and FYM supplied similar amounts
of total P in the dry solids. FYM applied to the field trials contained more
than four times the amount of K (0.62% ds) compared with other bio solids
(0.14% ds). As expected, the concentrations of trace elements in the plant
compost are larger than for FYM. The estimated N application from plant compost
ranged between (14 - 55.8), Farmyard manure (22.6 - 90) and chicken manure (30.7
- 122.8) kg N fed^-1 according to the rate of application.  Chicken manure contained the
greatest rates of Fe, Mn and Zn per ton or cubic meter. However, FYM contained
the greatest Cu rates applied to the soil.         Application of farmyard
manure to sugar beet significantly surpassed either plant compost or chicken
manure in plant height, root length root, shoot and biological yields per plant
and per feddan. The data show that regardless the bio solid type it is favorable to
apply the organic manures up to 9 t fed^-1 (15 m³ fed^-1). The greatest root and shoot yields per plant
and per feddan was attained when FYM was combined with the reduced rate of N.
The data also show the consistency of these biosolids as inputs for sugar beet
production. The inspection of the data revealed that biosolid
application effect could contribute in sugar beet yield plant^-1 with
50, 42.4 and 48.9 % and 50.41 and 50% per feddan for plant compost, farmyard
manure and chicken manure, respectively showing the practicality and possibility of safe use of
these bio-solids in minimizing the risks of inorganic fertilizers. It
could be concluded from this study that biosolids apply substantial macro and
micro nutrients with agronomic and economic value to such poor soils. Supplementation
with this major plant nutrient is recommended where they are frequently applied
to soil to maintain crop productivity.
