Girolamo Caruso (18 September 1842, Alcamo, province of Trapani – 2 January 1923, Pisa), was an Italian agronomist, university teacher and scientist.

Girolamo Caruso

Biography

He was born in Alcamo and graduated in Agriculture at the University of Naples in 1861. After spending some years in the army, first as a volunteer and later as commissioner of Military engineering, in 1864 he was appointed as teacher of agriculture at the agrarian provincial school of Corleone (Palermo), and its director until 1867, when he moved to Messina to teach at the Technical Institute.

In 1862, aged only 20, Caruso started to deal with crop rotation, nearly unknown in that period and, the following year, with reforestation of slopes and the creation of drainage basins to collect the waters to be used as power to irrigate the fields.

In those years he devoted himself to some research on agriculture in Sicily (on the gommosis of citrus trees, on viticulture and vinification, on olive growing) and got a great success with his work L'industria dei cereali in Sicilia e le popolazioni che la esercitano (Palermo 1870);[1] in this book, besides describing the agrarian techniques and machines, there were useful suggestions. Caruso recommended the system "a quinqueria" for the crop rotation (as in Sicilian manor farms), and indicated the agricultural tools available on the market.

In 1871, after winning a competitive examination for a professorship, he obtained the post as agronomy teacher (following Pietro Cuppari) and director of the Agrarian Institute at the University of Pisa, where he settled definitively; he had then different and important offices, above all by the Government.[2]

Thanks to his skilful guide, the Scuola Superiore di Agraria of Pisa became one of the most important institutes in its field and a pole of reference for Italian agriculture:[1] the pupils coming out from it, could apply, continue and extend, in Italy and abroad, the knowledges acquired and Caruso's works.

In 1872 he founded the Agrarian Comitium of Pisa which he presided over until 1919; Caruso used the work in the Comitium in close relationship with that of the university, promoting initiatives and debates in order to urge the competent authorities to improve the legislation for the agricultural field, or agrarian updating courses, exhibitions and meetings in order to stimulate the application of modern techniques.

In 1873 he presented an important introductory report about I sistemi di amministrazione rurale e la questione sociale; in 1875 he founded the magazine L'agricoltura italiana, which he ran until 1922 and had the purpose of divulging the innovation in the agricultural field and forming modern agronomists. The same year he took part in the fourth general congress of Italian farmers in Ferrara, where he presented the report: Sull'ordinamento dell'istruzione agraria.[3]

Caruso's thought is particularly evident in the introduction to his famous manual Agronomy, published in 1898 and used for many years in Italian universities, in which he affirmed: Italian agriculture is an art that you can practise empirically or according to the rules given by science; so there is an empirical agriculture and a rational one.[1]

In the book, he treated important subjects: irrigation, land development, soil management, and the study of tillage tools; inside it, there are also 263 printmakings depicting all the aspects of the agricultural environment and of cultivations. The schemes of the hydraulic-agrarian management, published in Caruso's book, are in all the university texts of Agronomy which have been edited until now; besides the nitrogen fertilization and irrigation are examined by linking theory to methods of calculation in a very modern way.

Superannuated from teaching in 1917, Girolamo Caruso died in Pisa on 2 January 1923.

On 12 November 1925, in the lecture room of Agronomy of Istituto superiore agrario of Pisa, they placed a marble bust of Girolamo Caruso, carved by Giuseppe Michelotti, similar to those of Cosimo Ridolfi and Pietro Cuppari, wanted by Caruso himself.

Alcamo, his native town, has remembered him by entitling him a street and the homonymous Technical Institute (now ITET).

The problem of the mezzadria system in Italy

In 1873, in one of his introductory reports, Caruso put in evidence the social, economic, and productive implications of the mezzadria (called metayage in English): first of all it had to exist, from the economic point of view, for the relationship that created between the farmer family and the land, that made possible the increase and sorting of the rural population even in far and less accessible areas, in addition to the growth of the quantity of work.[3]

According to him, however, the main reason for the convenience of this system was not the economic one, but the social one: connecting with the theory dear to Raffaello Lambruschini, Gino Capponi, and Bettino Ricasoli, he remarked the clear juxtaposition between the peaceful sharecroppers, "who loved order, property, family, laws", and the social dangerousness of day labourers.[3]

Research

When he started his university teaching, the modern mechanic tools for employment in the fields started to proliferate; besides getting interested in the study of all the main types existing at that time, Caruso also examined the economic results. His interest was also for the problems of a company structure and management, (with his Ricerche sull'ordinamento dell'azienda rurale, edited in Florence in 1894), and with the essay Sulla convenienza e sull'attuabilità del disegno di riforma agraria (in Atti della Accademia dei Georgofili, s. 4, Disp. 1, XXIII [1900], pp. 69–95).

He made memorable experiments on the mechanic threshing, on the new steam-powered oil mills, on the reaper-binder Aultmann, on the mowers Johnson e Aultmann, on the seed drill Cosimini, on the shelling machine Navacchi and machine press Blunt for conservation of forage into silos.

As regards tillage work he experienced the new types of plough Sack and Oliver, and the new systems of steam-powered ploughing, evaluating the working depth, the strength of mechanical traction and the methods of execution on level and slope.[1]

Girolamo Caruso was one of the first people to experience the chemical fertilization, first of all on wheat, and to appraise its efficacy; the first part of these experiences was published in 1888. In 1890 he determined the method for the calculation of the quantity of manure to be supplied, by using that method (today called the method of weighing) and affirming the necessity of the anticipation of the fertilizing elements, which was a complete innovation at that time.[1]

His constant activity of research is testified by his several notes presented at Accademia dei Georgofili and the essays published on l'Agricoltura italiana about viticulture and vinification (in 1878, 1892 and 1898); forages (1891); manures (1889, 1890, 1906, 1909); parasites of plants (1888–90, 1894–1897, 1902, 1915); olive growing; mechanised agriculture (1876, 1883, 1897). Besides, as he had known intuitively the importance of the type of manure used for soil, he studied and described, in detail, all the new fertilizers being produced, by putting them in comparison with those which were in use.[1]

In 1878 Caruso, being sure that the climatic conditions were responsible for the result of cultivations, set up a little weather station and since 1886 he daily published the detected meteorological data on the magazine L'Agricoltura Italiana.[1]

His scientific activity is documented by more than a hundred important publications; most of them are included in Atti della Regia Accademia dei Georgofili, and, more specifically, in the valuable magazine "L'Agricoltura italiana", founded by him in 1875 and directed for the rest of his life.

Girolamo Caruso was interested, above all, in the cultivation of wheat: he examined harvesting and sowing methods, fertilizing, pest management and cost of production. Under his guidance, the Institute got a high experience in this field, so that in 1925 they founded the Regional Institute for Cereal Growing, within the Agrarian High Institute (that is Istituto superiore agrario) of Pisa.

It must be noted, moreover, that in 1891 Nazareno Strampelli, the most important genetistic agronomist of the first half of the 20th century who produced new varieties of wheat, got his degree at the University of Pisa. He has the merit of having made possible the first green revolution, which is an improvement of the production capacity that made the Italian population self-sufficient.

Caruso also dedicated his studies to the cultivation of grapevine, and above all, to some kinds in the country Pisan, to green pruning, to the cultivation of vine without support, and to graftings on American cuttings to fight phylloxera.

Many of his studies included the fight against parasites, above all those of the vine and olive; until the first half of the 19th century Italian vines were unaffected by parasites, but in 1851 powdery mildew arrived, in 1878 Phylloxera and in 1879 downy mildew.[1]

Girolamo Caruso made some experiments on all systems of the fight against these parasites and engaged for their application in Tuscany and in Italy; besides, he carried forward different experiences on the methods of fight against click beetles of cereals, the grapevine moth, the olive fruit fly, la tingidae of pears, the insects harmful for the seeds in the granaries, the smallpox olive and morus-mildew.

Besides his studies of agronomy, he was rather interested in rural economy: on the production costs in the area of Pisa, in the usefulness of the manuring of olives with pomace, in the tests of manuring and cultural operations of wheat, the set of rules about farms, convenience and feasibility of the bill of land reform proposed by Maggiorino Ferraris and the legislation about the credit for land improvements and agrarian progress in general.[1]
