Spring into summer

In milk approximately 90% of the yellow color is because of the presence of -carotene, a fat-soluble carotenoid extracted from feed by cows. Summer milk is more yellow than winter milk because cows grazing on lush green pastures in the spring and summer months consume much higher levels of carotenoids than do cows ham-fed on hay and grain in the fall and winter. Various breeds of cows and even individual animals differ in the efficiency with which they extract -carotene from feed and in the degree to which they convert it into colorless vitamin A. The differences in the color of milk are more obvious in products made from milk fat, since here the yellow color is concentrated. Thus, unless standardized through the addition of colorant, products like butter and cheese show a wide variation in shade and in many cases appear unsatisfactory to the consumer. 

Garden compost can be classified as a medium-fertility soil improver (see pp.34-35). Apply it where required at an average rate of around 25 gal/50 sq ft (100 liters/5 sq m). This is a layer of approximately V2 in (1 cm) thick spread out evenly over the ground. Apply compost in spring or summer as a mulch, or dig it into the top 8 in (20 cm) of the soil. 

Fortunately I was right again, and winter began to thaw into spring. Before summer arrived, her son did, vrith Jacopo in tow.

During the late spring and summer of 1990 and 1991, a USGS study focused on herbicide transport into the atmosphere by various processes. This study was conducted prior to significant label rate reductions for atrazine-containing products. Once in the atmosphere, these compounds can be dispersed by air currents and redeposited by precipitation, snow, and dry deposition on the land surface, lakes, and streams. 

In August 1988, a new Black Sea invader - the ctenophore Mnemiopsis leidyi - appeared in the Sea of Azov it was first encountered near the Kerch Strait in the southern and eastern parts of the sea. From that time, every spring or summer, Mnemiopsis leidyi has penetrated into the Sea of Azov from the Black Sea with currents to provide an outburst in its development in the summer or early autumn. Then, it became extinct at the temperature drop below 4 °C at the end of October to November [28]. Mnemiopsis leidyi negatively affected the ecosystem of the Sea of Azov and undermined its fish stocks. 

Water runoff of the Kuban River was alternated after water diversion into the Nevinomysskiy canal in 1949 and especially as a result of the Krasnodarskoye reservoir construction in 1972 [26,33]. A total storage of this reservoir is 3.0 km3. The average water runoff at the delta head of the Kuban delta decreased from 13.0 km3 year-1 in 1929-1948 to 11.6 km3 year 1 in 1949-1972 and to 11.1 km3 year-1 in 1973-2000. Decrease in the suspended sediment load was more marked from 8.5 x 106 tyear 1 before 1949 to 6.8 x 106 tyear 1 in 1949-1972 and to 1.5 x 106 tyear 1 in 1973-2000. Reduction of suspended sediment load after the reservoir construction comprised 4.5 times (Table 11). Seasonal water runoff distribution was also alternated a share of the total annual runoff in spring and summer (especially from May to July) decreased, but in autumn and winter (especially from September to January) increased [5,26]. 

A summer peak and winter low were seen each year (Figs. 10.4 and 10.5), reflecting the fact that the tritium was displaced in large amounts in the higher parts of the atmosphere and leaked in the spring and summer into the lower parts.

Subsequently other trials were conducted to evaluate the efficacy of various types of cages taking into account the influence of variables such as time [33], whether death was natural or artificial [34], and the weekly holding capacity of dead bees, which, as mentioned previously, may be removed by different animals such as wasps and ants [35]. The latter study placed the holding capacity of the various kinds of receptacles in correlation with the environment (simphlied or complex) and season (spring and summer). 

Song (2004) reported that the relation between partial pressure of CO2 Pco ) temperature (T) in the surface water was obtained from the simulated laboratory experiments, which showed the formula Pqq =6.()2T+221.03. The relative error between the estimated Pqq and the measured values is lower than 4.5%. The air-sea flux seasonal distributions and strength of source/sink of CO2 in the East China Sea were obtained for the first time based on the data of surface seawater temperatures and partial pressure of the atmosphere. The seawater could take in CO2 from the atmosphere in the Bohai Sea, the Yellow Sea, and the East China Sea and the flux values are higher in winter than those in spring. In summer, the situation is reversed and CO2 is released into the atmosphere. In autumn, the seawaters can take in CO2 in the Bohai Sea and the northern Yellow Sea, but release CO2 into the atmosphere in the East China Sea and the southern Yellow Sea. The minimum and maximum of air-sea flux of adsorbed CO2 appear in autumn in the northern Yellow Sea (5.-3 g C/(m yr)) and in winter in the Bohai Sea (106.0 g C/(m yr)), respectively, and the minimum and maximum of released CO2 appear in summer in the northern Yellow Sea (-1.9 g C/(m -yr)) and the East China Sea (-18.8 g C/(m yr)), respectively. The annual mean fluxes from seawater to air are 36.8, 35.2, 21.0, and 3.5 g C/(m -yr) in the Bohai Sea, the northern Yellow Sea, the southern Yellow Sea, and the East China Sea, respectively (the Yellow Sea flux is 23.7 g C/(m -yr)), the East China Sea is the net sink of atmospheric CO2 in spring and winter, which can take in 7.69 and 13.56 million tons of carbon, respectively, and is the source of the release of CO2 into the air with 4.59 million tons of carbon. The Bohai Sea and the northern Yellow Sea are the sink of atmospheric CO2 and can take in 0.27 million tons of carbon. The southern Yellow Sea and the eastern China Sea are the source of CO2, which releases into the air 3.24 million tons of carbon in autumn. As a result, the net carbon sink strength of the East China Sea is 3.24 million tons of carbon in autumn. The annual mean sink strength of atmospheric CO2 in the seas east of China is 13.69 million tons of carbon.
