  This experiment was carried out at the  which poultry farm  of  Babylon to study the effect of adding humic acid to the drinking water on performance of Ross 308  broiler chicks . The experimented the period from  20/1/2017  to 5/3/2017of birds age  , A total of 135 one day old chicks were used in this experimented , chicks were allocated randomly in                     to 3 treatments, 45 chicks for each treatment , each treatment was included 3 equal replicates, 15 chicks for each one. 
 
The treatments , were: -
 
Treatment (T1)  basal diet + fresh water without addition (Control group).
 
Treatment(T2)  basal diet + fresh water supplemented with Humic acids in  ( 3.6 g/l liter water .
 
Treatment(T3)  basal diet + fresh water supplemented with Humic acids     ( 7.8 g/l liter water .
 
       The results of this experiment indicated that  supplemented of Humic acids in the fresh  water  during the period (1-6) week of the experiment , had a significant effect ) P≤0.05) on body weights rate of chicks and accumulative feed consumption , accumulative weights gain of the birds  and significant effect) P≤0.05) of feed conversion rate as compared with the control treatment. Addition of humic acid has an significant effect of the birds  ) P≤0.05) on the carcass traits  of birds (The relative weight of the various carcass cuts  and Internal organs )  in comparison to the birds of  control treatment.

The experiment was conducted in accordance with randomized complete design C. R. D in the private orchard in Fadhiliya village / Bashiqa district, Naynwa governorate during the growing season of 2012, to study the effect of treatment of olive trees Olea europaea L.  by different concentrations of Humus and extract seaweed, which included experience using Humus addition three levels 0, 4 and 8 ml.L^-1 and seaweed extract(Seaforcel) three levels 0, 4 and 8 ml.L^-1 sprayed trees until all the moisture from seaweed extract three times during the growing season, first in 18/ 3 and 18/4 in the second and third in the 18/5/2012. All measurements were taken at mid-October 2012.
 Results showed superiority concentration 8m.L^-1 Humus addition treatment gave increscent in fruit weight, length, flesh weight and N concentration. The effect of the interaction has exceeded the treatment of interaction between 8 ml. L^-1Humus and 8 ml. L^-1 seaweed extract in both the fruit weight and % of total nitrogen, while the treatment of the mixture was 4 ml. L^-1Humus and 8 ml. L^-1. A seaweed extract in the fruit-length ratio, while the interaction treatment exceeded 8 ml. L^-1. Humus and 0 ml. L^-1 seaweed extract in the average of flesh weight of fruits and excelled the treatment of interaction 8 ml. L^-1 Humus and 4 ml. L^-1 extract of seaweed in both of % oil in fruits and % of total protein.

The experiment was carried out in the poultry  at Babylon to study the effect of Humic Acid in the diet on performance of Ross 308  Broiler chicks   During the first period which extended form the 1st to the 6th week The period From 20/1/2017  to 5/3/2017 . A total of 180 one day old chicks were used , chicks were allocated randomly in to 4 equal treatments, 45 chicks for each treatment , each treatment was included 3 equal replicates, 15 chicks for each one. Treatments were arranged as follow:
      The T1 treatments fed of  Basal diet (Control group) and  T2 treatments fed supplemented with Basal diet + 2.4 g/kg Humic Acids  and T3  treatments fed supplemented with Basal diet + 4.8 g/kg Humic Acids  and  T4  treatments fed supplemented with Basal diet + 7.2 g/kg Humic Acids  .
   Results showed the following ; Addition of Humic Acids in the diet Broiler chicks during the period (1-6) week of the experiment , had a significant effect ) P≤0.05 (on body weights of Broiler chicks and accumulative feed consumption , accumulative weights gain and feed conversion rate as compared with the control treatment. Addition of Humic Acid significant effect  on Carcass traits (Dressing percentage , The relative weight of the various Parts and Internal organs )  in comparison with control treatment .

This experiment was conducted in accordance with randomized complete design (C . R . D ) in AL- Hosseinieh date palm Station of Karbala during the season of  2015 to study the effect of foliar spray with three levels of Humic acid (0 and 9 and 18 g.L-1) and three levels of  compound fertilizers (0, 4 and 8 ml.L-1) on  date Palm ، cultivar Maktoom. The off shoots were sprayed at three interval in tenth day of march , may and they were also sprayed with 0.2 %  urea one day before each spraying . Results were collected in mid-December. Results showed that Humic acid at 18ml.L-1 increased the chlorophyll a compared to Control , also Humic acid addition was superior increasing nitrogen, phosphorus, potassium and total protein in the leaves .
 
  The compound fertilizers (N.P.K) in concentration (8 g.L-1) significantly increased the chlorophyll a and b and  concentrations  nitrogen , phosphorus , potassium and total protein in the leaves .
 
The interactions between concentration 18 ml.L-1 of Humic acid and 8 g.L-1of compound fertilizers (  N.P.K ) significantly increased the chlorophyll a and b and  concentrations  nitrogen, phosphorus, potassium and total protein in the leaves on all other interaction .
