On the other hand, the mycorhizes of their roots in their average century and of life have fixed several hundreds of kilos of atmospheric nitrogen in the form of underground nodules that have enriched the poor, argillaceous, calcareous and stony ground where the roots are introduced.
Every spring is born several broods from small birds in the nests that the birds construct on their branches. A pair of hoopoes year after year takes advantage of a hole in the doubling trunk to bring to world one or two broods. The carob tree is, really, a complete ecosystem where hundreds of species of insects, arachnids, birds, small lizards and rodents find a comfortable habitat where to live, to feed themselves and to procreate.
Its dense foliage of dark and coriaceous leaves has given shade to my ancestors during many decades. At noon they sat down, we sat down, in the ground on coats of stuffed esparto of straw in the fresh shade of the old carob tree to eat bread with tomato, salt and olive oil, accompanied by sobrasada, parched cheese, botifarrones, camaiot, bacon roast on live coals, olives flavored with salt and fennel and a few figs dessert droughts, all this watered with a jet of red wine of own production drunk directly of a pumpkin of slim waist, Lagenaria siceraria, with a cork done with a small branch of olive tree. Memory with nostalgy the many sweet hours that I happened playing under this tree in my childhood and the flavorful thing and that felt like their carob beans to me. A pair of them filled the stomach to me and they cleared the hunger to me. They were my picnic. It accompanied sometimes them with some crude almond, that I cracked on a stone.
The carob tree is original of the Eastern Mediterranean. The Phoenicians and the Arabs extended their culture by all the Mediterranean river basin. It is a very resistant tree that supports very well the drought and the torrid sun of the summer. It prefers the good drained limestone grounds since their roots do not support flooded lands. The micorrhizal symbiontic fungi that surround their roots need to breathe to live. The static water prevents the soil oxygenation and drowns to the symbiotic fungi. Without filamentous and white hyphae of the fungus, the carob tree cannot absorb the water and the minerals of the ground and the nodules by the roots cannot fix the nitrogen of the air. It is understood since this enormous leguminous support better one releases drought that the water suspended in its roots, which would drown the micorrhizal fungi and it would suppose the death of the tree by starvation.
This dependency easily verifies when seeding seeds of Ceratonia siliqua in individual flowerpots. If the land of the flowerpot lacks spores of the symbiotic fungus, the small tree just born, after consuming the nutrients that the seed contained, stops growing, yellows, it languishes slowly and it ends up dying. In order to avoid that the young carob tree dies literally of hunger, it is sufficient with adding to the flowerpot a little earth picked up of underneath an old carob tree that contains thousands of spores of the symbiotic fungus, which germinate quickly, his hyphae surrounds the roots of the dying little tree and in few days the miracle takes place. The apical yolk appears vigorously and its growth is spectacular. If a few months later migrates the little tree to a greater flowerpot, is verified like its roots are surrounded by a species of white spiderwebs that smell of good earth. They are hyphae of the micorrhizal symbiontic fungi. Also small stuck gray small balls are the roots. They are the nodules locking devices of atmospheric nitrogen that contribute natural installment to the carob tree.
The pulp also is used in confectioner's like substitute of the chocolate. Mixed with wheat flour rich very spongy buns take control of her. The modern ices-cream dealer include the flour of carob bean in their chocolate ice creams and most bold they exclusively make ice creams of carob bean. Also an excellent sweet liquor can be done almost black letting ferment the flour dissolved in water to which grape grains are added to him to contribute necessary leavenings for the fermentation.
In the zone of Spanish Levante, for the production of establishments of carob trees in the breeding grounds, usually they are used the seeds gathered of the excrements of the cattle, since one knows that its germination is almost of the 100%. In industrial arboriculture on a large scale it is put under the seeds to the action of a sulfuric acid solution concentrated during one or two hours. Another method to break cuticle and to make it permeable to the water consists of submerging garrofines in boiling water and leaving them in soaking while it cools off during 24 - 48 hours. A simple very effective homemade method consists of cutting to a small piece of cuticle with a nail clippers to each carod seed in the cleared part opposed the germinal yolk. This simple method less than accelerates the germination in 10 days.
Carod seeds have a very uniform size and a weight. This characteristic drew attention of the old Arab and Jewish jewelers, used who them as unit of weight for their transactions of gold and precious stones. KIRAT called it with the Arab word = Carat. From KERATONIA comes the scientific name there to him = Ceratonia, that is to say, tree of the carats.
The carob trees can be masculine, feminine and hermaphrodite. Generally the nurserymen reject the masculine feet or graft by the methods of small shield or Majorcan chip with feminine or hermaphrodite yolks. Knowing him sexuality the carob tree is intelligent intercalary some masculine copy in the plantations from feminine carod trees.
